magnetic
Definition
Magnetic means something that can attract or repel other magnets or objects made of magnetic materials. For example, a magnet can attract a paper clip or a piece of iron.
Magnetic materials are made up of tiny particles called atoms. The atoms in magnetic materials have unpaired electrons. Unpaired electrons are electrons that spin in opposite directions. This creates a magnetic field around the atom.
When a lot of atoms with unpaired electrons are close together, their magnetic fields combine to create a strong magnetic field. This is what makes a magnet attract or repel other magnets or objects made of magnetic materials.
How can the word be used?
The compass needle is attracted to the magnetic field of the Earth.

Etymology
The word "magnet" comes from the Greek word "μαγνῆτις λίθος" (magnē̂tis líthos), which means "Magnesian stone". This is a reference to the Magnesian region of Greece, where lodestone was first found. Lodestone is a naturally occurring magnet that was used by the ancient Greeks to make compasses.
The Greek word "μαγνῆτις λίθος" is thought to be derived from the name of the Magnesian tribe, the Magnetes. The Magnetes were a people who lived in the Magnesian region of Greece. They were known for their use of lodestone, and they were said to be able to control the movement of iron with their magnets.
