System with a rotating magnet
The measuring systemConstruction:In the hollow coil is a pivotally positioned magnet. Attached to the shaft are a needle and spring, which are used for power supply and also holds a pointer to zero .

4Electro-magnetic system with a rotating coil
Measuring systemConstruction:In the cavity between the magnetic pole attachments is a magnetic coil pivotally placed in an aluminum frame. Attached to the shaft are a needle and spring, which are used for power supply and also holds a pointer to zero.

5Electro-magnetic system
Principal function:Passing a current through the coil creates a magnetic field, which tries to turn the coil so that the direction of the magnetic flux coincides with the direction of the magnetic flux of the permanent magnet.
