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.

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.
The two main types of electrodynamometer are attracted disc type and moving coil type. In the attracted disc type, two stationary coils create a magnetic field that attracts a disc attached to the moving coil. In the moving coil type, the coil is suspended between stationary magnets and experiences a force when current flows through it.

A moving coil galvanometer is a type of scanning device used in the transportation and trucking industry. The vehicle is pulled through a fixed scanner while an operator watches a closed circuit television.
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.
A solenoid coil is commonly used in audible locking systems. When an electric current passes through the coil, it creates a magnetic field that generates a sound by moving a plunger to actuate a locking mechanism.
Voltmeters provide a direct, difference of potential measurement or test.
Voltmeters are connected in parallel in a circuit.
