What is a subatomic particle?

Back

A subatomic particle is a particle smaller than an atom, which includes protons, neutrons, and electrons.

What is the difference between a permanent magnet and an electromagnet?

Back

A permanent magnet generates a constant magnetic field, while an electromagnet's magnetic field can be turned on and off with electric current.
