A transparent protective case contains a horseshoe-shaped permanent magnet. We can find a coil among its poles. The magnet is fixed, but the coil is attached to a mobile axis that, in addition, has got a needle and a spiral spring incorporated.\u00a0 The instrument also has got a group of graduated scales and several inputs to connect it to the circuit according to the magnitude we measure.<\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

When the device is connected between two sections of the circuit, the electric current goes through the coil.\u00a0 According to the theory of electromagnetism, in that instant the permanent magnetic field of the magnet begins to exert a force over the coil. As a consequence, this moves around its axis and the needle deviates a bit from its initial position.<\/div>

The steering angle is equivalent to the intensity of the current that goes through the veil. This allows to graduate the scale of the device if we employ currents with a known value. The same instrument allows us to measure intensities (connecting it in series), or differences in power (if we connect it in parallel).<\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

In 1882, Jacques-Ars\u00e8ne d\u00b4Arsonval\u00a0conceived the first device that measured the intensity of the current. It was made up of a permanent magnet and a moving coil that hangs from spiral springs.\u00a0\u00a0<\/span><\/p>

In 1888, Edward Weston\u00a0developed a commercially available form of this instrument. It became a standard component in measurement equipment for electric and electronical circuits.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
