1. The stack of magnets works as one big bar magnet. Do the poles change when you divide the magnet into pieces? 2. In step 3 of the experiment, do both sides of the magnet attract the metal surface? Explain how a single magnet can repel the rest of the stack, but still stick to the other surface. 3. How does the magnet attract something that is originally non?magnetic? 1. Describe the direction of the compass needle as you moved...

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....
