The accompanying figure shows a rectangular coil consisting of 35 closely spaced turns that has a resistance of 7.0 N. The magnetic field at all points inside the coil varies according to B = Boe-at where Bo - 0.50 T and a = 200 s-1. 2.0 cm 5.0 cm

What is the direction of the induced current in resistor A when coil B is moves to the left and then stops moving? there is no current O from left to right O form right to left

A bar is moved along conducting rails at a constant 2.0 m/s in the presence of a 1-tesla magnetic field into the page, as shown. A 4-ohm resistor is connected into the circuit. a) What current flows in the loop? b) What force is required to maintain the constant 2 mis velocity? c) How much work must be done by this force in 1 second? d) Calculate the power dissipated by the resistor and compare the energy dissipated by the resistor with the work done in this same time.

When you move a magnet through a 1 loop coil you detect a voltage of 0.001 volts, what voltage would you read if you move the same magnet at the same velocity through a coil with 1000 loops (assume the radius of the loops in the coil is the same as the one in the single loop wire)
