At a certain instant,coil A is in a 10-T external magnetic field and coil B is in a 1-T external magnetic field.Both coils have the same area and are oriented at right angles to the field.Which coil will have a greater emf induced in it?
A)coil A
B)coil B
C)It is impossible to know without more information about the fields.

Question

Quizplus · Accepted Answer

The induced emf depends on the rate of change of the magnetic field, not just the field strength. Without information on how the fields are changing, we cannot determine which coil has a greater induced emf.
