The region of influence around a magnet can be represented by magnetic field lines. The magnetic field around a bar magnet always forms:
Closed loops
Helical lines
Open loops
Straight lines
Tej examines the magnetic field around a bar magnet using compass and iron particles and then draws magnetic field lines on a paper. Which of the following represents the correct magnetic field lines around the bar magnet ?
How can we obtain magnetic field lines around a bar magnet?
Define magnetic lines of force. By drawing a neat diagram show magnetic field around bar magnet.
Earth's magnetic field lines are non-uniform while the magnetic field around a bar magnet is uniform:-
