The levitating effect can be created by alternating current or pulsed dc current. I bought a pulsed dc power supply that put out 101.3 volts and a commercial electromagnet. The magnet is strong. I put it face down on a steel work bench and had a hard time pulling it off by hand. I tried using it...
My understanding is that nonferrous metals like aluminum will levitate, but ferrous metals (steel, iron, etc.) will not. The attraction of ferrous metals to the electromagnet is stronger than the levitating force produced by the eddy currents in the plate.
From what I've read, the thickness...
I understand the basic principles of how a nonferrous metal will levitate. I wanted the polarity to be constant for an experiment. Since charged particles traveling through an homogenous magnetic field experience the Lorentz Force, I wanted to see if aluminum particles, charged by Eddy Currents...
This could be done with AC, but I want the magnetic field to always have the same polarity, say with North facing up, and South facing down. With AC the field would be constantly reversing every time the current changes direction.
As for stepping the voltage back down to return to the PWM...
I need advice on assembling a pulsed dc electromagnet.
I'd like to experiment with eddy current levitation. I've seen educational videos where a pulsed DC electromagnet will generate eddy currents in a plate of aluminum, which creates is own magnetic field, and causes the plate to levitate due...
Hello to all. I'm a new member and selected the nickname Skatterbrain, mainly because I have a hard time focusing on work with all of the physics questions rattling around in my head. I've found some great information reading your questions and answers. Hope I can get mine answered and maybe...
