Question

define magnetic field line . write it three properties

Answer 1

It is defined as the path along which unit north pole would tend to move if free to do so in a magnetic field.

properties are:

1)the lines of forces never cross each other .

2)magnetic lines of forces are closed curves which start in air from N-pole and end at S- pole and then return to N-pole

through the interior of the magnet .

3)magnetic lines of forces passes through conductors and insulators .

Answer 2

Answer:

this is your ans
