Question

Magnetic lines of force

• A. Have more directions
• B. Have no physical reality
• C. Can be used to indicate the direction of the magnetic field of a point
• D. All the above

Answer 1

The correct option is C

Can be used to indicate the direction of the magnetic field of a point

Magnetic lines of force form a definite pattern around a magnet. Whenever we have to find the direction of the magnetic field at a point around the magnet, we just draw a tangent along the magnetic line at that point.This tangent gives us the direction of the magnetic field at the mentioned point.
