To make a magnetic compass, magnetize a needle by rubbing it with a magnet, then float the needle on a small piece of cork or paper in water. It will align itself with Earth’s magnetic field.

Yes, the compass needle will show similar behavior when a magnet is brought closer. As a magnet itself, the needle will align with the external magnetic field, showing attraction or repulsion depending on the poles.
Placing a piece of wood between the compass needle and the magnet will not affect the compass needle’s deflection. Wood is non-magnetic and does not interfere with the magnetic field or the compass needle.
To keep magnets safe, store them with keepers (soft iron bars) across poles to prevent demagnetization. Avoid dropping, heating, or placing them near electronic devices, and keep them dry to prevent rusting.
Different magnets lift varying numbers of pins due to differences in their magnetic strength, size, and material composition. Stronger magnets have a more intense magnetic field, enabling them to attract and hold more pins.
