Question

State how the magnetic field produced by a straight current carrying conductor at a point depends on mark (a) current through the conductor (b) distance of point from conductor

Answer 1

I is directly proportional to B
R is inversely proportional to B

I-Current
R-Distance

Answer 2

Answer:

Strength of magnetic field produced by a straight current carrying wire at a given point is

(a) Directly proportional to the current passing through it.

(b) Inversely proportional to the distance of that point from the wire.
