NettetThe reason of current flow in a metallic wire is the flow of free electrons present in it. When a metallic wire is not connected to a source of electricity the electrons present in it are free to move in all directions. As a result, there is no net flow of current in the wire. NettetOpen Circuits . Current will only flow IN A CIRCUIT . ... Any interruption in the circuit , such as an open switch, a break in the wiring, or a component such as a resistor that has changed its resistance to an extremely high value will cause current to cease.
NettetThe magnetic field made by a current in a straight wire curls around the wire in a ring. You can find it by pointing your right thumb in the direction of the current in the wire and curling your fingers. Your fingers will be curled in the same direction as the magnetic field around the wire. A magnetic field around a wire with current moving upward NettetWhen a conducting wire \( X Y \) is moved towards the right, a current flows in the anti-clockwise direction. Direction of magnetic field at point \( \mathrm...
