Also curious about the effects of an EMP on a wind generator that uses a permanent magnet alternator. I guess if the EMP magnetism was strong enough it could over heat and burn up the wire coils, not really sure of the effect on the permanent magnets.

I’ve read where it can actually magnetize an engine to the point it won’t even move. What steps can we take for our homes to prepare in case of an attack of this sort ?

Also, magnets are going to lose their magnetic attraction/charge eventually, right? Regardless, I still want to make a magnet-powered generator.

Please help

When the rising magnet reaches the top of the cylinder, it gets toppled out and falls. The gravitational potential energy turns into kinetic energy. The magnet lands on a lever which turns a reciprocating handle on a generator. Each time the magnet lands on the lever, the handle turns once fully around, thus converting the kinetic energy into electricity.

The magnet tumbles back into the cylinder, again with the north pole facing down, and the cycle repeats.

Why can’t this continue indefinitely, with free energy being continuously extracted?

Electromagnetism is the physics of the electromagnetic field, a field that exerts a force on particles with the property of electric charge and is reciprocally affected by the presence and motion of such particles.

A changing magnetic field produces an electric field (this is the phenomenon of electromagnetic induction, the basis of operation for electrical generators, induction motors, and transformers). Similarly, a changing electric field generates a magnetic field.

The magnetic field is produced by the motion of electric charges, i.e., electric current. The magnetic field causes the magnetic force associated with magnets.

The theoretical implications of electromagnetism led to the development of special relativity by Albert Einstein in 1905; and from this it was shown that magnetic fields and electric fields are convertible with relative motion as a four vector and this led to their unification as electromagnetism.

You can also add some comments about electromagnetism, your feedbacks, or opinions regard it. THANKS SO MUCH!
