About this episode

This episode discusses the relativistic nature of magnetism and its relationship with electric forces.

Interesting Things with JC #1672: "Magnetism is a Relativistic Force" – A current-carrying wire stays electrically neutral on a table while a moving charge beside it feels a magnetic force, but in the charge’s own frame the spacing of charges changes and the same force appears electric.
