A magnetic weapon is one that uses magnetic fields to accelerate and propel projectiles or to focus charged particle beams. There are many hypothesised magnetic weapons such as the railgun and coilgun which accelerate a magnetic (in the case of railguns; non-magnetic) mass to a high velocity or ion cannons and plasma cannons which focus and direct charged particles using magnetic fields.Railguns use two parallel metal rails connected to a power supply.
