Question

Study the diagram alongside carefully and answer the following question:

When the current is made to flow through a copper conductor, the direction of the magnetic field set up by the conductor is:

Options

• Parallel to the direction of magnetic field of permanent magnet.

• At right angles to the direction of magnetic field of permanent magnet.

• In any direction to the direction of magnetic field of permanent magnet.

• None of these

Answer 1

At right angles to the direction of magnetic field of permanent magnet.

Explanation:

The magnetic field set up around a current-carrying conductor consists of concentric circles lying in a plane perpendicular to the conductor. Here, this field acts at right angles to the horizontal magnetic field of the permanent magnet.
