Question

Magnetic field intensity due to a straight current carrying conductor of finite length derivation

Answer 1

Magnetic Field produced by a current carrying straight conductor are concentric circles whose centre lie on the wire.

The Magnitude of Magnetic Field produced by a current carrying straight conductor at a given point is -

1) Directionally proportional to the current flowing through it.

i.e. B is Directionally proportional to I.

If current is increased then Magnetic Field produced by it is stronger.

2) Inversely proportional to distance r from the center.

i.e. B is Inversely proportional to R

Magnetic Field is stronger at a point which is near to the center and goes on decreasing on moving away from the center.

this is the answer
