A bar magnet is moved (in the plane of the page) with respect to a single-tur of radius 5.00 cm as shown (the coil lies in a plane perpendicular to the di of the bar magnet). Over a time interval of 0.150 s, the magnitude of the magnetic field at the coil varies from 0.640 T to 0.240 T. The resistance of coil is 2.50 Ohms. Assume that the magnetic field is uniform over the bounded by the coil. 4....

in a lecture demonstration, a bar magnet is moved toward a 2,000 "turn" circular coil such that the magnetic field is perpendicular to the area inside of the coil and increases uniformly from 20.0mT to 130.0 mT in 0.250 s. The diameter of the turns is 15.0 cm and the entire coil has a resistance of 3.00 ohms. What is the current induced in the coil and how much energy is produced as "Joule heat" in the wire turns over...
