  1. A conducting loop has a magnetic flux through it. If the loop is rotated will the flux through the loop change?

    Yes, if the rotation axis is not parallel to the magnetic field

    Only of the rotation axis is parallel to the magnetic field

    Yes, for any rotation axis

    Not enough information

2. A bar magnet is held stationary inside a coil of wire that is connected to a meter. What can be said about the current in the coil?

The current is increasing

The current is decreasing

There is no current

Not enough information to say anything about the current

3. A conducting loop is pulled from a region with a magnetic field through the loop to a region with no magnetic field. What can be said about the induced current and induced magnetic field?

There is no induced current

The induced current produces an induced magnetic field in the opposite direction of the external field.

The induced current produces an induced magnetic field in the same direction of the external field.

There is an induced current, but it does not create an induced magnetic field.

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...

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...
