0 votes

asked Mar 20, 2022 in 12th Physics by varun (6.7k points)

Magnetic lines of force due to a bar magnet do not intersect, because

Options:
(a) a point always has a single net magnetic field
(b) the lines have similar charges and so repel each other
(c) the lines always diverge from a single point
(d) None of the above
