Coil Wire Around Iron: Wrap insulated wire around an iron core (nail). Apply Current: Pass an electric current through the wire. The iron becomes temporarily ma

Pass a magnet over the mixture. Iron filings will be attracted to the magnet, leaving the sand behind.

Electromagnets: Electric current flowing through a coil creates a magnetic field. This field interacts with a permanent magnet, causing vibrations that produce

Magnetic force weakens significantly as the distance between magnets increases.

A compass needle aligns with Earth's magnetic field lines, pointing roughly North-South.

Magnets have two poles. Unlike poles attract (North-South), like poles repel (North-North, South-South).

Suspend Freely: Hang the magnet. The end pointing roughly north is the North pole. Use a Known Magnet: Approach the unknown magnet with a known North pole. Attr

Field: The region around a magnet where its influence is felt. Force: The push or pull exerted by a magnet on another magnet or magnetic material.

Powerful magnets create a repulsive force, lifting the train slightly above the tracks for reduced friction and increased speed.

Magnetize a needle and allow it to float freely on water or suspend it on a thread. The needle will align itself with Earth's magnetic field, pointing North-Sou

Iron and steel are both magnetic, but steel is generally stronger and more difficult to demagnetize.
