Concept explainers
To Explain:Whethera generator can be made by mounting permanent magnets on a rotating shaft while keeping the coil stationary.
Answer to Problem 10SSC
Yes
Explanation of Solution
Introduction:
A device, which changes motive power (or mechanical energy) into electrical power (used in external circuit), is called an electric generator. Electric generators work on the principle of
In spite of the coil being stationary, there is relative motion between the coil and the magnetic field which is sufficient to make a generator. Though, because of this, the power of the generator would be small due to small relative velocity of the magnets and the coil.
Conclusion:
A generator can be made even if the coil is stationary.
