We’re told that magnetism and electricity arise from the same source, but they behave very differently IRL. Magnetic force can be felt at a distance without a medium, but only as an attraction or repulsion. Electric potential needs a conductor of some kind, ionized air molecules at the least–and when it arrives, it can do a lot of damage! I’d love a simple explanation of how they differ and how they are linked.

There are no magnetic monopoles. In order for a magnetic field to exist, there must be both a source, and sink. That is the fundamental asymmetry in Maxwell’s Equations.
