The basic EFPA uses a voltage source and a combination of circuitry to accelerate an object to a desired speed. This is what makes EFPA a fairly unique device. An Electromotive Force Projectile Accelerator demonstrates many of basic concepts of magnetic machines. An EFPA is an example of an electromagnetic coil/solenoid. Such appear practically everywhere‚ from car door locks to doorbells and from diskette drive ejectors to fuel injectors. The only difference is that most solenoids limit the range
Premium Capacitor Magnetic field Rectifier
Saturable reactor or magnetic amplifier is a circuit that used to control very large load of AC with very small input DC. The saturable reactor consists of three essential elements : Direct current source‚ magnetic core with windings‚ and alternating current source. How it work? The AC load circuit run on to magnetic core and the DC control circuit is also went on to the same core. Ac current flows through winding and Since this current is alternating‚ the flux set up in the magnetic circuit loop is
Premium Alternating current Inductor Magnetic field
(CETS)‚ by which electrical energy may be transmitted‚ without electrical connection or physical contact‚ through nonmagnetic media of low conductivity. The CETS‚ which has been used to transfer up to 5 kW across a 10-mm gap‚ employs high-frequency magnetic coupling and enables plug-in power connections to be made in wet or hazardous environmental conditions without the risk of electric shock‚ short circuiting‚ or sparking. Energy may be transmitted without the necessity for accurately manufactured

Premium Magnetic field Gravitation
Electromagnetic induction where whenever a conductor cuts magnetic flux‚ dynamically induced electromotive force is produced‚ and this causes current to flow if the conductor/conductors is closed. The direction of induced current is given by Fleming’s right hand rule. A DC generator consists of these vital parts: o Yoke- It is the outer frame of a DC and it is made up of cast iron or steel. It carries the magnetic flux produced by field
