Question

A rectangular coil with dimensions of 8.0 cm×10 cm is dropped from a zero magnetic field position to a 1.4 T magnetic field in 0.10 s. The coil has 60 turns and is perpendicular to the magnetic field. What is induced emf in the coil as a result of this?

Answer 1

Explanation: 6.72v

According to the formula for induced EMF

EMF = NBA/t

where

N = no of turns

B=magnetic flux density

A=Area in meters

t= time

EMF= (60)(1.4)(0.08)(0.1)/0.1

EMF= 6.72V
