Search coils and credit cards. one practical way to measure magnetic field strength uses a small, closely wound coil called a search coil. the coil is initially held with its plane perpendicular to a magnetic field. the coil is then either quickly rotated a quarter-turn about a diameter or quickly pulled out of the field. (a) derive the equation relating the total charge q that flows through a search coil to the magnetic-field magnitude b. the search coil has n turns, each with area a, and the flux through the coil is decreased from its initial maximum value to zero in a time ât. the resistance of the coil is r, and the total charge is q = iât, where i is the average current induced by the change in flux. (b) in a credit card reader, the magnetic strip on the back of a credit card is rapidly âswipedâ past a coil within the reader. explain, using the same ideas that underlie the operation of a search coil, how the reader can decode the information stored in the pattern of magnetization on the strip. (c) is it necessary that the credit card be âswipedâ through the reader at exactly the right speed? why or why not?

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius í
=0.381meters and mass í=3.1íí. initially í"is on the ground and í#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of í#just before it strikes the ground. assume the pulley bearing is frictionless.
