Determined Quote by Pieter Zeeman
“According to well-known electrodynamic laws, an electron moving in a magnetic field is acted upon by a force which runs perpendicular to the direction of motion of the electron and to the direction of the magnetic field, and whose magnitude is easily determined.”
About This Quote
Source Scientific literature: Electrodynamics textbooks, 19th century
The magnetic force on a moving electron is always perpendicular to both its motion and the magnetic field, determining its trajectory.
In simple terms: Magnetic force is sideways to motion and field.
Key Takeaway
Remember direction when analyzing charged particle paths.

When I talked to Kelly [George Carlin's daughter] about it, she said that George Carlin once took her at about 12 years old and said, "I've figured it out."
