Question

9. Magnetic field due to current through a straight conductor explain

Answer 1

A current carrying conductor starts acting like a magnet and develops a magnetic field around it.

The directon of magnetic field can be found by using Right Hand Thumb Rule.

It states that,if we grasp a current carrying conductor in the palm of our right hand,such that,our thumb points in the direction of flow of current,then the curling of our fingers give us the direction of magnetic field around the condutor. (it can also be used for circular current carrying conductors.)
