but that says nothing as to why not or how much power you could get out of a device that switches a series of magnets on and off like a 3 phase induction motor.
In effect take a three phase induction motor and replace the rotor with a generator coil and bolt it in place so it cannot...
1) In a steady electromagnetic field, the act of passing a wire through it to cut the flux will induce resistance in the wires generating the field as well. (Not an electrical engineer/did really badly in the course where I learned that/may be wrong). Similarly I believe the current running...
self exciting dynamo question
I was reading about dynamo's and there was one that the power it made was used to run the electromagnet that made the magnetic field that the induction coil spun in.
This got me thinking if a generator can make enough electricity to power an electromagnet that is...
so the number of windings in the stator coil should be 60,000
if the voltage is 120 and the teslas of the magnets are 1 and the area of the magnetic field is one centimeter and if the field is moving at .2
-1*(-120/(1*.01)/.2)
then to use electromagnets as the motors the formula is:
B * gap = Mu...
Homework Statement
I am trying to work out the size of the field coil in a self-exciting generator as well as the size of the induction coil and the speed it all has to move
Homework Equations
I think Faraday's law is what I need but I am not sure I am not a physics student so finding...
