A coil is suspended around an axis which is colinear with the axis of a bar magnet.The coil is connected to a resistor with ends labeled “a” and “b”. The bar magnet moves from left to right with North and South poles labeled as in the figure. UseLenz’s law to answer the following question concerning the direction of induced currents and magnetic fields.What is the direction of the induced magnetic field in the coil when the bar magnet ismoving from...

. A permanent magnet is dropped south-end-down through a horizontal circular coil with a radius of 10 cm, having 200 turns, and a total resistance of 5π ohms. Find the magnitude and direction of the current induced in the coil when the magnet has passed through and the field through the coil is decreasing at 40 mT/s.

If a magnet is dropped through a copper tubing, the induced current then creates its own magnetic field. What is the direction of the currents magnetic field?
A flashlight can be made that is powered by the induced current from a magnet moving through a coil of wire. The coil and magnet are inside a plastic tube that can be shaken causing the magnet to move back and forth through the coil. Assume the magnet has a maximum field strength of 0.05 T. Assume that the radius of the coil is 1.5 cm and the magnet is shaken with a frequency of about two shakes per second....
