site focuses mainly on the reluctance coilgun although future
updates will look more closely at the induction version. For an
overview of the beginnings of electric gun research see .
The use of a non-conducting tube is preferred because with a conducting
tube there is a large electromagnetic braking effect as the magnetised
projectile moves through it. Slotting of the tube can help with
reducing eddy current braking if a conducting tube must be used.
It is termed a reluctance coilgun because the force acts to move
the projectile in the direction of decreasing magnetic reluctance.
