I can't seem to figure out how to solve this problem. If you are given the solenoid length and diameter. And told it consists of a single layer of tightly wound wire with the diameter of the wire given, the change in current thru the wire given, and the change in time given how would you find...
Hello all,
We've been studying electromagnetism and motors in physics. I was just wondering, if you placed a rotating magnet near the end of a current-carrying solenoid, what would the relationship be between the magnet's speed of rotation and the induced voltage in the solenoid?
Thanks
Hello. My ride-on Lawn Mower broke down recently. And I'm not a real mechanics or automobile person so please help me out. (it requires a bit of knowledge on circuits)
When I turn on the ignition, usually the engine rev's a bit. And then I try it a couple times until it works. Takes about 2~3...
if we were to insert a search coil inside a solenoid, (plane of coil perpendicular to B), would the induced current change direction in the middle of the solenoid ? it would have to wouldn't it since it would now be approching the opposite pole ---
