A moving coil galvanometer is a device used to measure small electric currents. It consists of a coil of wire suspended in a magnetic field, which causes the coil to move when a current is passed through it. The movement of the coil is proportional to the strength of the current, allowing the device to provide a measurement of the current passing through it.

What are the types of galvanometer?
The two main types of galvanometers are moving coil galvanometers and moving magnet galvanometers. Moving coil galvanometers use a coil of wire that moves in a magnetic field, while moving magnet galvanometers use a magnet that moves in a coil of wire.
Is megger related to hot wire instrument moving coil or moving iron?
Megger is related to a hot wire instrument with a moving coil. The megger uses a moving coil to measure insulation resistance in electrical circuits and equipment. This type of instrument is specifically designed for insulation testing.
Moving a magnet in and out of a coil of wire produces an?
electric current in the coil of wire.
Differences between Permanent magnet moving coil and moving iron?
Permanent magnet moving coil (PMMC) instruments use a moving coil that is suspended between the poles of a permanent magnet, whereas moving iron instruments use a stationary coil and a moving iron piece that moves within the coil's magnetic field. PMMC instruments are more accurate but have limited range, while moving iron instruments are less accurate but can measure higher currents. PMMC instruments are inherently more expensive compared to moving iron instruments.
What is the effect of moving into a coil of more loops?
Moving into a coil with more loops increases the magnetic flux linked with the coil, resulting in a higher induced electromotive force (emf) in the coil. This leads to a stronger current being induced in the coil due to Faraday's law of electromagnetic induction.

Write the construction of a moving coil galvanometer?
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.
