Solution :
d = 230 m
Number of turns int he coil : N = 135
Change in current : ΔI = 6.10 x 106 A - 0 = 6.10 x 106 A
And, Δt = 10.9 μs = 10.9 x 10-6 sec
radius of the loop is : r = 0.8 m
.
Here, Magnetic field due to the lightening at the position of loop will be :
.
And, Average induced emf is given by :
Since, Area of the loop is given by : A = π r2

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. A 108-turn circular coil with a radius of 0.835 m is oriented perpendicular to the magnetic field as shown. The magnetic field at the coil drops from 4.30 x 10 3 T to 0.00 T in 10.5...
Magnetism 1. (4) An unknown particle travelling at a velocity of 2.20x106 m/s to the right as seen by an observer, enters a region that has an electric field of magnitude 750 V/m pointed away from the observer. Ignore gravity for this question. (a) What is the direction and magnitude of the perpendicular magnetic field which would best cancel out the effect of the electric field so that the particle passes through undeflected? (b) If while travelling 0.200 m, with...
Need help solving problem 4 Consider the magnetic circuit below. All 3 coils have equal turns N- 20. Assume the core is linear with a permeability of p 5x10 H/m, average length i- 2x 10* m, cross section area A- 1 x 10 m2 Ignore the core losses and copper winding resistance. The current flowing though the top coll is sinusoidal with an ms value of 10 A and frequency of 60 Hz) Determine the following: 1) Reluctance of the...
