Levitating Magnet with Load of 12oz: Shielding Electronics & Transmitter

AI Thread Summary
A powerful electromagnet can levitate a 12oz load, but the challenge lies in transmitting wireless signals through its strong magnetic field. Shielding electronics with a thin metal sheet may protect them, but it could hinder the wireless transmitter's functionality. Concerns about data transmission interference from the magnetic field are raised, prompting questions about effective shielding methods like Faraday's shield or Mu-metal. The magnetic field is likely DC, which could pose risks to microcontrollers, sensors, and Bluetooth devices. Seeking advice before experimentation is crucial to avoid damaging components.

So basically i have this powerful electromagnet that generates an electromagnetic field that can levitate another magnet and withhold a load of 12oz and still levitate:

My problem is, I want to be able to use electronics and send wireless signals through this strong magnetic field. I can shield the electronics with a thin metal sheet but my wireless transmitter cannot have this protection, since it would essentially prevent radio transmission. Additionally, even if the transmitter can be allowed to transmit, the magnetic field would have some major interference on the data transmission(right?). So I was wondering if you guys know of any special way to shield the transmitter so that
1) the electronics shielded within this magnetic field won't fry
2) the signal gets transmitted

Is a faraday's shield even going to be effective in this situation? Should I consider Mu-metal instead? Or do a combination?

Is the magnetic field ac or dc? If it is dc, what electronic component do you expect to fail? If it is ac, what frequency is it, and how large is it (Gauss)? Are you sure the magnetic field will have an effect on the circuits? Have you tried it?

I'm fairly sure that the magnetic field is dc, since it has an ac/dc adapter. I'm thinking of having a microcontroller and various sensors, as well as bluetooth and perhaps a wireless transmitting mini camera. These are all pretty barebone parts from sites like sparkfun, so I don't think that they will be safe from the magnetic field. And then of course there is the problem with the signal transmission.

I haven't tried all this yet since I'd like to seek some advice before I accidentally destroy something :/

thanks for the help
 
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
