Magnetic Field due to Straight Conductor
Magnetic Field Due To Current Through A Straight Conductor
The magnetic field lines around a current carrying straight conductor are concentric circles whose centre lies on the wire. To visualize the pattern of the magnetic field around a straight current—carrying conductor, we will do an experiment:
Take a stiff copper wire and pass it through the centre of a card board. Then, connect a battery source, a variable resistance through a switch i.e. K as shown in the figure
Place a compass on the cardboard and start the current by closing the switch. Compass needle get deflected and its deflection show the direction of magnetic field.
1. Mark the position of the north pole of the needle on the cardboard.
2. Place the compass ahead so that the south pole of the needle lies at the point marked for the previous position of the north pole.

10thA marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.
