Expert Solution
Step 1
Solution:
From the above-given figure,
The formula for the power delivered by the magnetic field of magnitude B onto the bar of length L that is moving to the right at speed v with current I flowing through at time t it is calculated as:
Step 2
We know that,
Power delivered(P) =Magnetic force x speed
But as per the given data,
The Magnetic force acting on the field is given as:
