Detailed Solution

The deflections in the magnetic needle when brought near the current carrying wire depicts that the current and magnetism are related.
The current-carrying wire produces a magnetic field; if we place a magnetic needle near it, it deflects from the zero point. This is because of the induced magnetic field. Hence by the deflection of the needle, it can be stated that current and magnetism are related to each other.
