Nickel, iron, cobalt
Magnetism
The properties of attraction, possessed by magnets
Magnet
An object that makes a magnet field.
Lined up domains in the same directions.
Domains
Groups of atoms inside magnetic materials, that act like tiny magnets
Core
A magnetic material put inside a coil to make an electromagnet
Magnet field line
The lines that iron filings make when they are in a magnetic field
Electromagnets
A coil of wire with an iron core and a current through the wire
Magnet field
The area a magnet is affected by a magnetic force
Poles
The parts of a magnet where the magnetic effects are the strongest.
Magnetic force
The force of repulsion or attraction between the poles of magnets.
Coil
Formed when a conductor is wound around a core or form to create an inductor or electromagnet
