The parts of a bar magnet at which the magnetic effect is strongest are called the
Answer Details
The correct answer is "poles". A bar magnet has two poles, a north pole and a south pole. These poles are the points on the magnet where the magnetic field is strongest. When a bar magnet is freely suspended, it will point in a north-south direction, aligning itself with the Earth's magnetic field. This is because the north pole of the magnet is attracted to the Earth's south magnetic pole, and vice versa. The strength of the magnetic force between two magnets or a magnet and a magnetic material depends on the strength of the magnetic field, which is greatest at the poles.
