electromagnet
That would be an electromagnet.
Michael Faraday was the first one who observed the production of electricity by moving magnets towards a coil of wire. This phenomenon is known as electromagnetic induction.
An electric motor. In a motor the coil spins within the magenetic field producing mechanical energy. In a generator the magnet spins within a coil to produce electricity. in either case the magnets can be either solid fixed magents or electromagnetic coils.
Moving coil galvanometre is a device which is used to detect current in a curcuit.
The function of the moving coil is to deflect the instruments needle across a calibrated scale to give the meter operator an accurate reading of what ever he is testing. The moving coil is given a minute current, through internal instrument circuity, a sample of the potential that is being measured.
There are three coils in Air circuit breaker.. 1.Solonoid coil 2.Moving coil 3. fixed coil
it is dc

Because you are moving it through the earth's magnetic field.
Different b/w a moving coil instrument and a moving iron instrument
The coil will produce an alternating electric current.
The coil will produce an alternating electric current.
Fans are comprised of both coils and magnets. When the fan is turned on, an electric current is sent through the coil in the fan and will move around in a circle. Because electricity emits a magnetic field, the magnets in the fan will be attracted to the magnetic force emitted by the electricity moving around in the coil and the fan will start to spin.
No. Magnets create an electric feild, not electricity.However, when you spin a magnet inside a coil of wire (or you can spin the coil of wire instead), you will create an electrical current.
A moving coil Galvanometer consists of a coil PQRS which is wound over a non metalic frame having soft iron core in the middle. This Coil Is suspended in b/w a powerful magnet poles N-S with the help of Phosphor Bronze wire. Concave mirror is fixed on d suspending thread upside the coil through which deflection can b noted by Lamp and Scale arrangement. The lower end of the coil is connected by hair spring.
It is related to moving coil type instrument
Electromagnetic induction.
the force of objects being attracted by magnets. the coils or solenoids act as magnets and the projectile (which must be able to attract to magnets, often iron or steel is used) is attracted to the coils. but when the projectile reaches the coil the coil must be turned off so the projectile keeps going instead of stopping at the coil.
