How can I do a Very Strong Electromagnetism device? Answered
Hi, I want to do a electromagnetic device, that must be like a cilinder, because I will put a "armature" to protect that.
I need 7500 Gauss, or near this. I dont know how materials is necessary and the wire, spins, turns. If I do anything wrong is possible that device will be very hot and dangerous. This device can not be very big (can be 20cm and diameter like a 2,3cm). Voltage is not a problem.
