Magnetism

Magnetism is a force of attraction or repulsion that occurs between two magnetic objects.

A magnetic field is the area around a magnet where magnetic forces can be observed.

They repel each other.

They attract each other.

The shape of a magnetic field can be visualized using iron filings, which align along the field lines.

The Earth produces its own magnetic field, which is similar to that of a bar magnet.

Materials like iron, nickel, and cobalt are attracted to magnets.

Iron filings are used to visualize the invisible magnetic field lines.

Magnetic poles are the ends of a magnet where the magnetic force is strongest; they are labeled as north and south.

Permanent magnets maintain their magnetism over time, while temporary magnets only exhibit magnetic properties when in a magnetic field.
