The direction of magnetic lines of force produced by passing a direct current in a conductor is:
A. perpendicular to the conductor & coming outwards
B. parallel to conductor
C. surrounding the conductor and of circular nature
D. perpendicular to the conductor & coming inwards
Answer:
C. surrounding the conductor and of circular nature
The direction of magnetic lines of force produced by passing a direct current in a conductor is surrounding the conductor and of circular nature.
Explanation:
The right hand screw rule is used to determine the direction of magnetic lines of force produced by passing a direct current through a conductor. Magnetic lines of force extend radially outward, perpendicular to the conductor. Surrounding the conductor and having a circular shape. The electric current flowing through a wire generates heat, which is why an electric circuit becomes hot after a while. This is due to the resistance of the wire. The higher the resistance of the wire, the greater the current loss in the form of heat in the circuit. As a result, The direction of magnetic lines of force produced by passing a direct current in a conductor is surrounding the conductor and of circular nature.
