Faraday's Law — Loop Moving in FieldHardQuestion 20225

Question

A conducting loop moves at constant velocity through a uniform magnetic field region. While fully inside the field, the induced EMF is:

A
Maximum
B
Equal to BLv
C
Zero
Correct
D
Decreasing with time

Correct answer

Zero

Explanation

While fully inside a uniform field, flux through the loop is constant (does not change with position) → dΦ/dt = 0 → EMF = 0. EMF is only induced when the loop is entering or exiting the field boundary.
