Question

what are magnetic field lines?​

Answer 1

${\huge{\underbrace{\overbrace{\color{grey}{answer}}}}}$

The magnetic field is a region or space where there is an influence of a magnet. There are different types of magnets. Bar magnets, rod magnets, horseshoe magnet, ring magnet etc. All types of magnets have two poles; North Pole which is indicated by ‘N’ and South Pole which is indicated by ‘S’. Irrespective of shape every magnet has a field around it. For the better understanding of the magnetic field, place an iron nail in a particular distance from the magnet. Suddenly it gets attracted towards the magnet. If the iron nail is far away from the magnet, it will not have any influence. The area where the power of magnet exists is known as magnetic field or B field.
