PHY 102 Electromagnetic Induction 1 Objective Question

Question

What is the primary cause of 'Motional EMF' as described in the document?
Options
A A fixed loop in a magnetic field that changes with time.
B A loop moving in a uniform and constant magnetic field.
Correct Answer
C A loop changing its shape in a constant magnetic field.
D A loop at rest in a constant magnetic field.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 17 introduces 'Motional EMF' by stating: 'Now try moving the loop in a uniform and constant magnetic field. This changes the flux, too.' This implies the movement of the loop is the cause.

Hint

Consider the name 'Motional EMF' and the introductory text for that section on page 17.
