A flashlight can be made that is powered by the inducedcurrent from a magnet moving through a coil of wire. Thecoil and magnet are inside a plastic tube that can be shakencausing the magnet to move back and forth through thecoil. Assume the magnet has a maximum field strength of0.05 T. Make reasonable assumptions and specify the sizeof the coil and the number of turns necessary to light astandard 1-watt, 3-V flashlight bulb.
Magnets carrying very large currentsare used to produce the uniform, large-magnitude magnetic fieldsthat are required for magnetic resonance imaging (MRI). A typicalMRI magnet may be a solenoid that is 2.0 m long and 1.0 m in diameter,has a self-inductance of 4.4 H, and carries a current of 750 A. Anormal wire carrying that much current would dissipate a great dealof electrical power as heat, so most MRI magnets are made with coils of superconducting wire cooled by liquid helium at a temperature justunder its boiling point (4.2 K). After a current is established in the wire,the power supply is disconnected and the magnet leads are shorted togetherthrough a piece of superconductor so that the current flows withoutresistance as long as the liquid helium keeps the magnet cold.Under rare circumstances, a small segment of the magnet’s wiremay lose its superconducting properties and develop resistance. In thissegment, electrical energy is converted to thermal energy, which canboil off some…
A straight conductor of length I moves with an acceleration a = 0.1 ms2 at right angles to a magnetic field of uniform strength B = 10 T. The e.m.f. between the ends of the conductor increased from 0 to 5 V during the first 20 s after the beginning of motion. Calculate I and give your answer in SI units.
A conducting crossbar is in electrical contact with two vertical conducting wires and slides down those wires, pulled by gravity. The wires are connected with a 10 Ω resistor R to form a closed circuit as shown in the figure. The mass of the crossbar is 30 gm and its length ` between the vertical wires is 0.5 m. There is a horizontal magnetic field B = 1 Tesla perpendicular to the plane of the loop. a) What is the induced current needed to counterbalance the force of gravity? b) Indicate the direction the current is moving and why this is the direction. c) How fast will the crossbar be moving after the initial period of acceleration?
