A traditional pointer voltmeter includes a sensitive ammeter with a permanent magnet inside. A coil made of a wire is connected in series between the two terminals of the ammeter. The coil is placed in the magnetic field of the permanent magnet and is connected to the pointer of the meter through a transmission device. Most voltmeters are divided into two ranges.
