Magnetic Generator Q And A’s

Urgent question about electric generators?

2. September 2011

So does an electric generator produce current when a magnet is making contact with the coil, or is it just the magnetic field? Do generator run out, or go bad (say because the magnet loses its magnetism, or the coil wears down)? Does it matter what the coil is made of (nickel, copper, aluminum, etc.)

Are Magnetic Generators Effective?

I’ve been doing some research trying to find out if magnet generators are effective, and if so where is the best place to purchase the specs to make one. Supposedly, you CAN build them yourself with very little investment, and they will generate electricity throughout your whole house. I’m just hoping to find someone who [...]

I understand when the copper coil spins within the magnetic field, the current is produced. I just dont know how the magnets that are NOT permanent magnets get magnetised initially???????
