NGSS

A measure of the net positive or negative particles in an object

Electric charge

A measure of the net positive or negative particles in an object. Electric charge. Electric charge is the property of particles that causes them to attract or repel each other.

A flow of electric charge, it is measured in amperes (A)

Electric current

A flow of electric charge, it is measured in amperes A. Electric current. In simple terms, electric current is how fast electricity moves through a wire or circuit.

A temporary magnet made of wire coiled around an iron core

Electromagnet

A temporary magnet made of wire coiled around an iron core. Electromagnet. An electromagnet is a magnet created by electricity flowing through a wire coil, often wrapped around a metal core.

A material that does not let electricity pass through easily

Insulator

A material that does not let electricity pass through easily is called an insulator. In simple terms, an insulator is a material that stops electricity from flowing, like rubber or plastic around wires.

The area around a magnet where its magnetic force acts

Magnetic field

The area around a magnet where its magnetic force acts is called a magnetic field. A magnetic field is the invisible space around a magnet where it can push or pull on other magnetic objects.

The part of a magnet where the magnetic force is strongest

Magnetic pole

The part of a magnet where the magnetic force is strongest magnetic pole. A magnetic pole is where a magnet's pull or push is the strongest.

The properties and interactions of magnets

Magnetism

The properties and interactions of magnets. Magnetism. Magnetism is a force that attracts or repels objects due to the motion of electric charges.
