A freely-suspended magnet swinging in a horizontal plane comes to rest with its axis pointing approximately
Answer Details
A freely-suspended magnet will come to rest with its axis pointing approximately north-south. This is because the magnet aligns itself with the Earth's magnetic field, which runs approximately north-south at most locations on the planet. As the magnet swings, it experiences a torque due to the magnetic field, which causes it to align itself with the field and come to rest with its axis pointing in the direction of the field.
