Question
A magnetic field line is used to find the direction of
- South-north
- A compass needle
- A bar magnet
- Magnetic field
Hint:
A magnetic field line is used to find the direction of the magnetic field.
The correct answer is: Magnetic field
- The centers of the concentric circles that make up the magnetic field lines caused by a straight wire carrying a current are located on the magnetic field.
- To determine the direction of the magnetic field, magnetic field lines are used.
