Question

If we change in the direction of the current passing through the wire near to the magnetic needle:

• A. position of the pole of the needle will change
• B. position of the pole of the needle will remain same
• C. change in position of the pole depends on the current intensity
• D. none of the above is correct

Answer 1

The correct option is A position of the pole of the needle will change

When the direction of the current flowing through the wire is reversed, direction of the magnetic field, so produced, also changes its direction which results in changing the position of pole of needle kept near the wire.
