Questions and Answers

What is electromagnetism?

Electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields. It is the dominant force in the interactions of atoms and molecules.

How can electromagnetism be thought of?

Electromagnetism can be thought of as a combination of electrostatics and magnetism, two distinct but closely intertwined phenomena.

What are the effects of electromagnetic forces between charged particles?

Electromagnetic forces cause an attraction between particles with opposite charges and repulsion between particles with the same charge.

What is the relationship between magnetism and charged particles in relative motion?

<p>Magnetism is an interaction that occurs exclusively between charged particles in relative motion.</p> Signup and view all the answers
