Electromagnetics

Permanent Magnets

Magnets that attract objects containing iron, nickel, or cobalt. They maintain their magnetic properties without the need for an external power source, and their strength can vary based on materials and manufacturing processes.

Magnetic Field

The area around the magnet where the magnetic force or magnetism can be felt.

Electromagnets

Magnets created using electricity.

Coil of Wire (Solenoid)

A crucial component in creating electromagnets.

Power Source

An essential element for producing an electromagnet, typically a battery.

Magnetism & Electricity

The relationship between magnetic fields and electric currents.

Generator

A device that converts mechanical energy into electrical energy.

Electric Motor

A device that converts electrical energy into mechanical energy.

Opposing Magnetic Fields

Magnetic fields that create motion in electric motors.

Voltage

The potential difference that can change the speed of a motor.
