What is the shape of the magnetic field lines around a bar magnet?
Correct Answer: Closed loops
- Step 1: Understand that a bar magnet has two ends called poles: a north pole and a south pole.
- Step 2: Know that magnetic field lines represent the direction and strength of the magnetic field.
- Step 3: Visualize the magnetic field lines starting at the north pole of the magnet.
- Step 4: Imagine the lines moving away from the north pole into the space around the magnet.
- Step 5: Picture the lines curving around and heading towards the south pole of the magnet.
- Step 6: Recognize that the lines do not just stop at the south pole; they continue inside the magnet back to the north pole, forming closed loops.
