This bar magnet is surrounded by magnetized needles that show the direction of magnetic forces. Which of the following explain the magnetic forces that are being shown around the bar magnet.

• The magnetic force comes out of the north end of the bar magnet and into the south end of the bar magnet.

• The magnetic forces comes out of the south end of the magnet and into the north end of the bar magnet.

• The magnetic force comes out of the west end of the bar magnet and into the east end of the bar magnet.

• The magnetic force comes out of the east end of the bar magnet and into the west end of the bar magnet.
