Question

Which of the following produces magnetic field as well as respond to external magnetic field?

• A. Only magnets.
• B. Magnets and current carrying wires
• C. Only current carrying wires.
• D. none of these

Answer 1

The correct option is B

Magnets and current carrying wires

Magnetic effects are both produced and experienced by magnets and current carrying conductors.

The experiment of sprinkling iron filings on a cardboard with a current carrying conductor kept normal to the board demonstrates the magnetic effects of current carrying wire i.e. moving charges.
