Final answer:
A point directly above the center of a magnet, between the north and south poles, would experience a stronger magnetic field than on the north side. The field lines between opposite poles are denser, indicating a stronger field in that region. A needle near a magnet's north pole will magnetize, creating a repulsive effect towards the same pole of another magnet.
Step-by-step explanation:
The question asks whether a point to the north side of a magnet or directly above the center would experience a stronger magnetic field. According to the principles of magnetism, magnetic field lines are denser and therefore stronger between opposite poles of magnets. If you place a point north of a magnet (where the same pole is present, e.g., north to north), the magnetic field lines would repel each other, making the field weak in that area. In contrast, directly above the center of the magnet (between the north and south poles), the field lines are denser, indicating a stronger magnetic field in this region.
A needle brought close to the north pole of a magnet will become magnetized. The end of the needle nearest the north pole of the bar magnet becomes a north pole itself and thus repels the north pole of another magnet, and conversely, attracts the south pole. Therefore, if a needle is aligned along the axis of a bar magnet and just outside the north pole, the point closest to the bar magnet will repel from the south pole of another magnet.
