A device (a tranducer) which converts kinetic energy into electrical energy Dynamos are often used to produce a c electricity on a push-bike Unlike a full-blown generator, the rotor coil is replaced with rotating permanent magnets These magnets rotate near to the stator coil, (wrapped around a soft iron core) and cause a small current to flow (via electromagnetic induction)
The process in which the motion of electrical charges generated a magnetic field
Also known as "generator," a machine creating electric currents by relative motions between the conductors that carry them and magnets of electromagnets In geomagnetism the term is also used for naturally occurring fluid flows through a magnetic field, generating electric currents A self-excited dynamo (of either kind) is one in which the generated current creates the magnetic field by which the dynamo operates
generator consisting of a coil (the armature) that rotates between the poles of an electromagnet (the field magnet) causing a current to flow in the armature
