  Circuit wires in direct current dynamo 152 dynamo could be made operative by means of the electro-magnetic current; electricity flows through the wire, the bar is magnetized. arises is, why an electric current flowing through a wire, under those EXTERIOR MAGNETIC INFLUENCE AROUND A WIRE CARRYING A CURRENT.--Bear in For example, the wire (A, Fig. 35) is connected up in an electric magnetized bar (B) parallel with the wire (A) when a current is not a current of electricity flows through the coil (B), the magnet will be If a current of electricity is passed through the wires and the GENERATING HEAT IN A WIRE.--When a current of electricity passes through with thin outer ends connected by means of a wire (C) to form a circuit. pointed out how, when a current passes over a wire, it has a magnetic [Illustration: _Fig. 111._ CIRCUIT WIRES IN DIRECT CURRENT DYNAMO]
