PHY 102 Electromagnetic Induction 1 Objective Question

Question

For the easiest case, with a constant magnetic field (B) and a flat surface of area (A), what is the formula for magnetic flux (Φ_B)?
Options
A Φ_B = B + A
B Φ_B = B / A
C Φ_B = B ⋅ A
Correct Answer
D Φ_B = B x A
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 6 defines magnetic flux in the easiest case as Φ_B = B ⋅ A, where B is the magnetic field and A is the area vector.

Hint

The formula for magnetic flux involves a dot product between two vectors.
