PHY 102 Electromagnetic Induction 1 Objective Question

Question

How does moving a loop in a uniform and constant magnetic field induce an EMF, according to the document's explanation of 'Motional EMF'?
Options
A It changes the magnetic field intensity over time.
B It changes the area of the loop.
C It changes the magnetic flux through the loop.
Correct Answer
D It generates a static electric charge.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 17 states: 'Now try moving the loop in a uniform and constant magnetic field. This changes the flux, too.' Page 18 further clarifies: 'The flux is Φ_B = B⋅A = BDx. This changes in time:'.

Hint

Recall the definition of magnetic flux and how its components might change when a loop moves.
