If the number of coils in the wire is doubled from 100 to 200, and the original rate of 2 times per second is kept the same, what will be the new voltage induced?
physical science -
What does the "original rate" refer to? What is the device?
If it is some wound coil rotating in a fixed magnetic field, the voltage will double if the number of windings doubles. It is still one coil.
