1. What is electromagnetism at the subatomic level?

It is a fundamental force between charged particles

It is the force that holds subatomic particles together

It is a fundamental method to form tiny electromagnets

2. What happens when electrons travel though a metal wire?

The wire becomes anodized

Electrons only travel through a wire if a magnet is nearby

A magnetic field is formed around the wire
