MrHayman said:The coil creates a alternating magnetic field around it. This induces an opposing alternating magnetic field, from eddy currents, in the alluminum plate under the coil.
You can do it with a small coil of wire plugged directly into the wall, if the coil has the right reactance. To large a coil will be too heavy. To small a coil will melt. You need the metal plate and alluminum or copper is best.
Would be interesting to calculate how intense a field you would need to get enough inductive reaction from the air or vacuume. So you could do it without the metal plate.
"UFO-Electromagnetic Levitation Demonstration" is a scientific experiment that demonstrates the principles of electromagnetic levitation by using a UFO-shaped object as the levitating device.
Electromagnetic levitation is achieved by using opposing magnetic fields to counteract the force of gravity on an object. This is possible because of the properties of magnets and electricity.
The materials needed for this demonstration include a UFO-shaped object, a strong magnet, a power source, and a conductive material such as copper wire.
This demonstration can help to illustrate the principles of electromagnetic levitation and how it can be used in real-world applications, such as in maglev trains and other transportation systems.
It is important to handle magnets with caution and keep them away from electronic devices and pacemakers. Additionally, always follow proper electrical safety protocols when working with a power source.
