Magnetism II - JSS3 Basic science Past Questions and Answers - page 2

The two types of magnetic poles are north and south poles. Opposite poles attract each other, while similar poles repel.

The region around a magnet where its force can affect other objects is called the magnetic field.

To care for magnets, avoid dropping them, keep them away from high temperatures, store them away from electronic devices, and clean them gently with a soft cloth.

Magnets can attract materials like iron, nickel, and cobalt because they are made up of atoms with aligned magnetic fields, allowing them to be influenced by the magnetic force.

High temperatures can demagnetize magnets by causing the atoms within them to lose their alignment, disrupting their magnetic fields and reducing their overall magnetism.

To prevent magnets from becoming demagnetized over time, store them in pairs or with magnetic shielding to minimize exposure to external magnetic fields and keep them away from heat sources.
