Practical Coilgun Design

Want to know more about magnetism in coilguns? Want to know why and how electromagnets work? Want some math to help analyze coilguns?

For background, here are some relevent coilgun topics on "the theory of electromagnets".

Capacitors

What are capacitors?
What are the units of capacitance?
How do they insulate plates?
How does a capacitor discharge?
Can multiple capacitors store more energy?
How much kinetic energy from a capacitor?

Inductors

Projectiles

What kind of magnetic materials are there?
Consider the magnetic field and how it interacts with the projectile
Force - where does it come from?
