Question
A coil of conducting wire is connected to a device that measures current. Which action will not induce current in the coil? Assume that any magnetic field is directed perpendicular to the coil.
moving a second, current-carrying coil up and down rapidly near the first coil
moving the coil up and down rapidly in the magnetic field
applying a constant, uniform magnetic field of 15 T
varying the strength of the magnetic field between 0 T and 8 T

Explanation / Answer
It should be
applying a constant, uniform magnetic field of 15 T
Since change in flux is zero.
