Important questions for class 10 Science -

~ What are ‘magnetic field lines’? How is the direction of a magnetic field at a point determined ?​

Answer 1

Answer:

The area around a magnet where a magnetic force is experienced is called magnetic field.

Explanation:

Outside the magnet, the magnetic field lines are directed from N-pole of magnet towards S-pole. However inside the magnet the field lines are directed from S-pole to N-pole.. Thus magnetic field lines form a close loop.

The magnetic field line at any point, points in the direction of magnetic field at that point.
