EMP effects on Solar Panels and wind generators?

Tuesday, September 6, 2011

My house runs completely on solar panels and I’ve heard that an EMP weapon "Electro Magnetic pulse" would fry them making them useless. I’ve also heard talk of possibly protecting electronics underground, is this possible? and if so how deep would you have to go? Naturally what’s on your roof would be toasted so what’s [...]

Urgent question about electric generators?

Friday, September 2, 2011

2 Comments

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.)

Please give right answers. My life depends on it!!?

1: If you doubled the number of coils and doubled the voltage, what would be the increase in magnetic strength? It would remain the same, since 2 / 2 = 1 It would be 4 times as strong, since 2 x 2 = 4 You can’t increase magnetism by increasing the voltage 2: What causes [...]

Using magnetic force to generate electricity?

So, I understand how electricity is generated via a generator by using magnetism to jump-start a movement in [loose] electrons (like in that of copper); however, how far do the electrons go and is there a finite amount? If they’re moving along the atoms in the copper, what happens at the destination? Ah, I see.. [...]

In a generator, the current produced in __________ when the loop is parallel to the surrounding magnetic field. a. zero current b. average c. very small d. at a maximum Describe how a step – down transformer works to reduce voltage. Use the vocabulary terms “primary coil,” “secondary coil” and “electromagnetic induction.” A __________ magnetic [...]

Will a metal bracket interfere with a motor?

Hi, I wasn’t sure to place this question in engineering or physics, but it seemed more an electricity & magnetism question. I am attempting to build a bicycle pedal-powered generator. A bicycle stand’s roller will move the DC motor’s (aka generator’s) shaft. I understand I will need a blocking diode (with a large heat sink) [...]
