So I have a magnet that goes through a metal coil, north entering first, then exits through the other side of the coil. The induced current changes direction half way as the magnet is passing through the coil. So the question is:

Why does the induced current change direction when the magnet is halfway going through a coil? Be very specific when answering this one. (Address what is happening to the magnetic flux and the direction of the induced magnetic field.)

Written Problem: Induction from a falling magnet We have a small magnet with a magnetic moment of m = 0.1 Am2 (remember: magnetic moment is defined as m = IA - see page 932 of book for the definition). We also have coils of wire. The coils are made out of 100 circular loops of a single wire. A single loop has a radius of 10 cm. The thickness of the wire has a circular cross section with a 0.5...

1- A U-shaped conductor and conducting rod are used to form a slidewire generator. The generator lies in the xy plane with its conducting rod being parallel to the y axis and sliding along the positive x axis. A uniform magnetic field is applied in the positive z direction. If the velocity of the rod is doubled, what happens to the power dissipated by the generator's resistance? -It is quadrupled - It is doubled -It stays the same -It is...

If we move a refrigerator magnet back and forth, we generate an electromagnetic wave that propagates away from us. Assume we move the magnet along the z-axis centered on the origin with an amplitude of 10 cm and with a frequency of 2.0 Hz. Consider a loop in the xy-plane centered on the origin with a radius of 2.0 cm. Assume that when the magnet is closest to the loop, the magnetic field within the loop has a spatially uniform...
