Magnetic Filed Due to a Current Carrying Conductor

Magnetic Filed Due to a Current Carrying Conductor Points : Magnetic Filed Due to a Current Carrying Conductor When an electric flows through a. wire, a magnetic field is built up around the wire itself. This can be seen using a cardboard, iron filing, and a current carrying wire. When the wire passed though the cardboard and the current flowing, iron filings are sprinkled on to the card board. They can be seen arranging themselves in a magnetic field. The magnetic lines of force are referred to as flux. Just as in a natural magnet, the field is strongest near the wire and diminishes as the distance from the wire increases.
Flux around a wire does have direction. Flux direction is determined by the direction of electron flow thin the wire. The north pole of the compass needle indicates the direction of flux or magnetic field around the wire. The dot in the centre of the wire on the left indicated the point of the current direction arrow coming toward the observer; the x at the right represents the tile of the current arrow pointing away from the observers. If the direction of electron flow within the wire is reserved, the compasses needles will reserve themselves, indicating a change in a flux direction.
