A single turn coil of radius 7.00 cm is held in a vertical plane and a magnet is rapidly moved relative to the coil as shown in the diagram below. The field inside the coil changes from 0.045 T to 0.020 T in a matter of 0.300 seconds. If the resistance of the coil is 5.00 Ohms, what is the magnitude and direction of the induced current in a coil as viewed from the side of the magnet? Make sure to include clear explanations for your choice of current direction.
In the diagram above, a bar magnet is brought closer to a conducting wire loop with 7 Ω of resistance. As a result a uniform 3 A current is induced in the wire. What is the direction of the induced magnetic field at the center of the loop? Explain the reasoning behind your selection in detail.A) UpB) DownC) ClockwiseD) CounterclockwiseE) Cannot be determined
A circular loop of wire sits face on to 2 tesla magnetic field that points into the page, as shown in the upper diagram at right. The wire loop is turned a quarter turn by a crank, so that the right edge of the loop drops into the page and the left side of the loop comes out of the page. The radius of the loop is 20cm and the quarter turn takes 0.5 seconds. (a) What is the average emf induced in the loop, and does the current in the wire flow in the direction of the arrow on the loop or in the opposite direction? (b) If the crank continues to turn the loop another quarter turn in 0.5 seconds in the same direction, until it looks like the bottom picture, what will be the average emf induced in the wire, and does the current in the wire flow in the direction of the arrow or in the opposite direction?
