Students explore electromagnetism and engineering concepts using optimization techniques to design an efficient magnetic launcher. Groups start by algebraically solving the equations of motion for the velocity at the time when a projectile leaves a launcher. Then they test three different launchers, in which the number of coils used is different,

This motor-generator functions as a motor while being "charged" by spinning up to 6400 rpm; it functions as a generator when it switches to deliver its energy to the load (thus decreasing the rpm as it gives up its energy). To launch, this rotor-based kinetic energy is drawn off and converted to electrical power in a two- to three-second

*4Professor, Department Of Electrical Engineering, Sandip Institute Of Technology And Research Center, Maharashtra, India. The Electromagnetic Aircraft Launch System (EMALS) is a novel technology that has been implemented on modern aircraft carriers for the purpose of launching aircraft.
The EMALS energy-storage system design accommodates this by drawing power from the ship during its 45-second recharge period and storing the energy kinetically using the rotors of four disk alternators; the system then releases that energy (up to 484 MJ) in 2–3 seconds.
