Electricity and Magnetism

Static discharge is the sudden flow of electricity between two electrically charged objects, often observed as a spark, such as a lightning bolt.

Electric current is measured in amps.

A magnetic field is the region around a magnet where magnetic forces can be detected.

Conduction is the transfer of electric charges through direct contact between materials.

Nickel is an example of a ferromagnetic material.

Static electricity is the buildup of electric charge on the surface of objects, while current electricity is the flow of electric charge through a conductor.

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

A compass uses a magnetic needle that aligns with the Earth's magnetic field, helping to indicate direction.

Electromagnetic induction is the process of generating electric current in a conductor by changing the magnetic field around it.

This relationship is described by Ohm's Law: Voltage (V) = Current (I) x Resistance (R).
