Physics

the physics of the electromagnetic field: a field which exerts a force on particles that possess the property of electric charge

Electromagnetism

a form of gun that converts electrical energy into projectile kinetic energy

Railgun

the difference of electrical potential between two points of an electrical or electronic circuit

Voltage

is a material or object that produces a magnetic field

Magnet

is the tendency of a stream of fluid to stay attached to a convex surface rather than follow a straight line in its original direction

Coanda effect

a thin layer of flowing gas or liquid in contact with a surface

Boundary layer

is the force that resists the movement of a solid object through a fluid

Drag

The study of the properties of moving air and especially of the interaction between the air and solid bodies moving through it
