Question

A wire conducting an electric current is bent to form a loop. The magnetic field lines are bunched up inside the loop.

True

False

In the compass a magnet in the shape of a needle is used to find the direction of the North geographic pole.

True

False

An "electromagnet" is produced when we construct a current-carrying coil of wire.

True

False

Magnetic forces decrease with the distance from their source and the corresponding Law was discovered by:

Coulomb

Newton

Gilbert

None of the above

A current-carrying wire is placed between the poles of a u-shaped magnet. The wire is:
