move, when the coil will come to rest,and the pointer will indicate the angle of deflection of the coil. The magnetic field being practically uniform, the angle of ELECTRICAL MEASUREMENTS. 1673 deflection is closely proportional to the current in the coil,so the scale divisions are very uniform, as… … Fig. 1024. force set up in it which causes a current to circulate aroundthe bobbin as long as the bobbin moves. This current cir-culates in thie opposite direction to the current in the coil;hence, it tends to oppose the motion of the coil. Asthis tendency exists only when the bobbin is moving,…
