SuperMagnetMan HighTesla

[Music] welcome back to another super magnet man video or should I say SM magnetics you'll notice that I have the SM magnetic shirt on in this particular video I want to take a minute and explain how these two companies work SM magnetics is a sister company to super magnet man super magnet man is our commercial one we have our website we've been selling magnets for 15 years on the web through that website and before that on another website we have been selling magnets for a long time but one of the things that we noticed is many times larger companies would contact us companies that are making products companies that are needing special engineered solutions research universities and all of these so we wanted a separate entity that we could process that so we could handle it and meet their specific needs this is SM magnetics and that's the role that it plays for us this video is about the products that we developed for SM magnetics so many times when a customer may contact super magnet man they find themselves diverted over to SM magnetics that's because SM magnetics is better designed to handle these type custom-engineered requests or mass volume requests that you may have so we're going to take a look now you see this massive magnet sitting in front of me for many years I had been trying to develop a magnetic field that would help me obsolesce my Gauss meter my Gauss meter only reads up to 15,000 Gauss 1.5 tesla and so what we did is we had a request from a customer to develop a magnet that would be over to Tesla so we came up with this design and we had our factory make it for us and it worked out better than we expected this one is a giant magnet that has magnets and we'll use our pyramid design and we stack the magnets up and to show you the kind of fields that we're able to generate that this isn't a small volume we're in about a five millimeter square area and inside this area we're getting 25,000 Gauss we can stack these magnets up a little differently and we can get 28,000 twenty-nine thousand Gauss depending on how we arrange these magnets that we've stacked it up which is incredible to be able to get two point six two point seven Tesla out of a permanent magnet it's not supercooled this magnet is powerful enough to even magnetized neodymium magnets we can take small disc magnets like this and just take them take a magnet like this and as it gets close it jumps into the center and if it was unmagnetized it will magnetize it as soon as it enters the field we can pull it back out and it is permanent magnet is permanently magnetized so this magnet is strong enough to magnetize neodymium to demonstrate that this will magnetize neodymium material now let me let me make a little side claim we're not saying it's 100% saturation we have tested it it gets like 98 99 percent but this could vary between material types you can choose other materials that may have a higher degree of a higher requirement for magnetic field strength to magnetize them but these are measuring like 15 Gauss - two Gauss this is these are essentially dead magnets they were sent to us unmagnetized accidentally and so what we can do is we're just going to put it in there for a second now pull that magnet out and set it aside now we're going to take another one and you'll see how quickly it flies into the field once it's in the field all we have to do is pull it back out and you will see these two magnets are now magnetized and one of them the Gauss level will be it's at 1900 2000 Gauss which is pretty close to what we get with this size five millimeter about two millimeter magnet standard and twenty one twenty two hundred Gauss on this one so this is showing you that yes this magnet can actually magnetize neodymium magnets we have had other requests as people find the different things that we can do they bring us new challenges can you do this my favorite expression I love the question can you do this I tell them quickly we're electrical engineers for us all things are possible just add money and stir so by this what we want you to do is build the box around us tell us what your constraints are when do you need it how much should it cost and we work to develop the solution for you let me take you through a couple of examples that we've had an other request to take a look at the C magnet design as we like to call it what we've done is laid this out so we have our pyramid magnets we have a large magnet underneath it and then we have iron cobalt that is carrying the magnetic field all the way around so that it comes back and gives us the highest possible field on the surface of the regular platform we're getting about 1.7 Tesla but in this air gap once we start stacking other magnets on top depending on the configuration that we use we can either have a large area that is giving us something like 2.1 2.2 Tesla or we can give a little bit smaller area and push it up to 2.5 all the way up to 2.8 Tesla we are trying our best to get the three tests so we have a couple of other designs and the works that we think will get us over three Tesla that's sort of our inside the company goal now is to get over three Tesla with a permanent magnet that is not supercooled and that will be another video what we've got also is another design where we're looking at being able to have two sets of magnetic flux forcing into a smaller area and see what this design we're sending the designs to our magnetic engineer who is able to model this and give us back the data we work with them very carefully to design exactly what our customers need now this top one is a very special design that we had we had a customer that said hey well they saw this video and saw that we were getting over to Tesla and they saw a little article that I put on LinkedIn and they said can you make a two Tesla field that's 12 inches wide and it needs to be about four millimeter gap they had something and as most of our customers we may never know what they were using it for but they wanted a slot that they could slide the object through and see if it would stand up to two tesla fields I don't know whether they were testing it with it or what they were doing with it and most of the time that's something we never know they just tell us what their design objectives are so now we're going to take a look at that in a little bit more detail we want to take a look at this and this particular magnet we had to design an array that would get us to Tesla or more in a very small area but it had to be 12 inches long so you can see this is the general design and there's the slot that the object would be fed through when we looked at the magnetic field profile you can see the very intense red field in the middle this is where it's going over to Tesla and as a matter of fact you can see that across that profile it is very even from the very edge we actually made the design about 16 inches wide with a fourth a little over 12 inch wide slot but for the area where the slot is the field is 2.1 Tesla pretty much all the way across and it is very even all the way across so we look for customers to bring us challenges that let us take magnet technology to the next level to help you see one more of a really challenging customer request we had a request to produce an extremely large magnet this needed to have a pull force over a thousand pounds at a quarter of an inch so one of the designs that we came up with to do this was to take the magnets on the side and point them in pushing the flux to a set of magnets in the middle that we're pushing it straight up you can see the lines separating it as we look at it through this viewing film that the viewing film shows you the southern lines where the polls change what this magnet does is give us an extremely powerful field all across this surface we are measuring four thousand forty six hundred five thousand in the middle fifty-five hundred forty six hundred fifty three hundred fifty six hundred we have an extremely powerful field now keep in mind this is encased in stainless steel this was for an application around the ocean it was going to be used on ships and it needed to be protected so that it would not rust these magnets needed to be lasting for at least ten years whereas regularly if you don't have that kind of a plating on it you don't have stainless steel this type magnet would just erode away in a year or twos time this one is able to last a very long time because it's completely encased in stainless steel we also had two laser welded because magnetic fields that's powerful you cannot arc weld with them these are the kind of things that we work with customers to develop now one of the things to point out is we can't tell you about a lot of the products that we work with because we sign NDA's non-disclosure agreements with our customers so that we do not tell about most of the things that we do these are some of the things that we have done that aren't necessarily covered by an NDA and or there have been many many years ago that we did these but I wanted you to see many of the things that are coming out today we may have had a part in that you just don't know and we can't tell you and if you have a product that you want to keep secret and you want us to stay as your proprietary partner we would be delighted to work with you as well so as you look over your applications or your product development or your research that you're trying to do at a university contact us at SM magnetics or super magnet man and we'll get you to SM magnetics so that we can help you get exactly the right magnet for your application at super magnet man or SM magnetics we are always looking for customers who want to take their technology to the next level
