Question

What is the primary characteristic that distinguishes Motional EMF from EMF induced by a changing magnetic field in a fixed loop?
Options
A Motional EMF occurs only in superconductors.
B Motional EMF arises from the movement of the conductor through a magnetic field, rather than a time-varying field acting on a stationary loop.
Correct Answer
C Motional EMF does not depend on the magnetic field strength.
D Motional EMF only produces an electric field, not a current.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 17 explains that up until that point, fixed loops with changing magnetic fields were considered. Motional EMF is introduced as the case where the loop itself moves in a uniform and constant magnetic field, changing the flux due to movement.

Hint

Think about what 'Motional' implies in the context of EMF.
