You probably have heard it before, you just need to connect it to the physics terminology. The Lorentz force law says that a charged particle moving in a magnetic field experienced a force given by the cross product of the velocity and the magnetic field:

- klyrs 4y agoI'm well familiar with the Lorentz force! Did homework finding paths charged particles take through fields and everything. What's novel to me (if obvious in retrospect) is that a nontrivial electric charge/potential can be frozen within a chunk of dielectric. This is as fundamental as magnetism, and I'm somewhat buffaloed by the fact that electrets aren't more commonplace novelty items.
