A loop of wire is perpendicular to a magnetic field such that the field is coming straight at you through the loop. The field begins to decrease in magnitude. Which direction will the induced magnetic field be (toward/away from you) and which direction will the induced current in the wire be (clockwise/counter clockwise) ? Explain.

Inducted Magnetic field will be toward from you

Inducted current direction will be counter clockwise.

Explanation:

Lenz's law states that the direction of the current induced in a wire by a changing magnetic field is such that the magnetic field created by the induced current opposes the initial changing magnetic field.

So if the field begins to decrease, the induced magnetic field would try to stop this, so its direction will be the same as the magnetic field, toward from you.

This induced magnetic field is produced by the current in the wire. If the inducted magnetic field will be toward you, the right hand rule says that the direction from the inducted current will be counter clockwise.
