How does an ammeter work?

In the ammeter, a coil is placed between the poles of the magnet, fixed on the axis. The arrow of the device is attached to it.When a measured electric current flows through the coil, the forces from the side of the magnets act on the horizontal sections of the wires of the coil, in opposite sides of the coil currents flow in opposite directions, therefore the forces from the side of the magnets are directed oppositely. it rotates relative to the scale arrow of the device The coil spring prevents rotation of the coil. The coil stops rotating when the spring force balances the magnetic force.
