alleryA steady, unchanging magnetic flux through a circuit induces an emf of:
ASlowly falling
BExactly zero
CVery large
DSlowly rising
Answer & Solution
Correct answer: B. Exactly zero
1. The induced emf follows the rate at which flux changes.
2. If nothing changes, that rate is nothing.
3. So the induced emf is zero.
