Answer:
The induced current is
Explanation:
From the question we are told that
The number of turns is
The cross-sectional area is
The initial magnetic field is
The magnetic field at time = 1.02 s is
The resistance is
The induced emf is mathematically represented as
The negative sign tells us that the induced emf is moving opposite to the change in magnetic flux
Here is the change in magnetic flux which is mathematically represented as
Where dB is the change in magnetic field which is mathematically represented as
substituting values
Thus
So
The induced current i mathematically represented as
substituting values
