A lightning bolt strikes 30 m from a circular metal loop of area 0.5 m^2. As the lightning bolt current rises from zero to 6 x 10^6 amps in 10 microseconds, what is the magnitude of the average induced emf in the loop?
Please explain the process using non-calculus based
steps.

B = mu*I/2*pi*R
V = d(Fi)/dt
=Fi = B*A
=2*10^-7*6*10^6/30*0.5
= 0.02
V = d(fi)/dt
= 0.02/0.01
= 2 V

Problem 4 The bolt of lightning depicted in the figure below passes 230 m from a 135-turn coil oriented as shown. If the current in the lightning bolt falls from 6.10 X 106 A to zero in 10.9 us, what is the average voltage induced in the coil?

007 10.0 points A bolt of lightning, such as the one shown on the left in the figure, behaves like a vertical wire conducting electric current. As a result, it produces a magnetic field whose strength varies with the distance from the lightning.
