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? Assume the distance to the center of the coil determines the average magnetic field at the coil's position. Treat the lightning bolt as a long, vertical wire and ignore the 200 m...
A circular coil of radius 10.5 cm is located in a region of magnetic field where B(t) = (+0.2 T/s)t and with the magnetic field oriented perpendicular to the plane of the loop. Find the magnutide of the induced EMF in this loop at t = 11.5 s.
A lightning bolt produces a rapidly varying magnetic field. If the bolt strikes the earth vertically and acts like a current in a long straight wire, it will induce a voltage in a loop aligned like that shown in the figure below. What voltage is induced in a 0.90 m diameter loop 60.0 m from a 2.00x106 A lightning strike, if the current falls to zero in 25.0 us? (Discuss circumstances under which such a voltage would produce noticeable consequences.)...
In a lightning bolt, a large amount of charge flows during a time of 2.1 10-3 s. Assume that the bolt can be treated as a long, straight line of current. At a perpendicular distance of 30 m from the bolt, a magnetic field of 7.8 10-5 T is measured. How much charge has flowed during the lightning bolt? Ignore the earth's magnetic field.
A circular conducting loop with radius 2.70 cm is placed in a uniform magnetic field of 0.850 T with the plane of the coil perpendicular to the magnetic field as shown. ! The magnetic field decreases to 0.300 T in a time interval of 25.0 ms. What is the average induced emf in the loop during this interval?
A circular coil that has 120 turns and a radius of 10.0 cm lies in a magnetic field that has a magnitude of 0.0650 T directed perpendicular to the coil. What is the magnetic flux through the coil? (Express your answer to three significant figures.) The magnetic field through the coil is increased steadily to 0.100 T over a time interval of 0.300 s. What is the magnitude of the emf induced in the coil during the time interval? (Express...

An emf is induced by rotating a 1347 turn, 20.0 cm diameter coil in the Earth's 3.53 10-5 T magnetic field. What average emf is induced, given the plane of the coil is originally perpendicular to the Earth's field and is rotated to be parallel to the field in 10.0 ms?
A 23-turn circular coil of radius 3.00 cm and resistance 1.00 is placed in a magnetic field directed perpendicular to the plane of the coil. The magnitude of the magnetic field varies in time according to the expression B = 0.010 Ot + 0.040 ot, where B is in teslas and t is in seconds. Calculate the induced emf in the coil at t = 5.20 s. 2.77 If the flux is changing as a function of time, how do...
