Question

how is the strength of magnetic field near a straight current conductor (1)related to the strength of current in the conductor (2) is affected by changing the direction of flow of current in the conductor

Answer 1

Answer:

(1) the current flowing in a conductor is directly proportional to the strength of megnetic field .

(2) the direction of megnetic field around a straight current carriying conductor also get reversed if the flow of current get reversed.
