Question

The magnetic field in a particular region is independent of position, but varies in time as sketched in the figure below. If a loop of area 2.14 m2 is oriented perpendicular to this magnetic field, what is the approximate magnitude of the flux through the loop at t = 0.25 s?

The magnetic field in a particular region is independent of position, but varies in time as sketched in the figure below. If a loop of area 2.14 m2 is oriented perpendicular to this magnetic field, what is the approximate magnitude of the flux through the loop at t = 0.25 s?

Explanation / Answer


magnetic flux = NAdB

mag flux = 2.14* dB

mag flux = 2.14 dB

we need to find dB from figure at t= 0.25 secs, to get the final answer
