Answer to Question #122329 in Electricity and Magnetism for Aya

Question

Is there other ways to see the magnetic field lines around the bar magnet ?

Answer 1

We cannot see the lines of the magnetic field around the magnet because they are invisible. But we can see their effect on the magnetic arrow or magnetic sawdust and thus construct the contour of these lines. That is, you need to have either a compass or magnetic sawdust.
