Question

How is the strength of magnetic field near a straight current-conductor
(i) related to the strength of current in the conductor?
(ii) is affected by changing the direction of flow of current in the conductor?​

Answer 1

Answer:

$\huge\pink{AnSwer}$

(i) The strength of magnetic field around a straight current conductor increaseson increasing the strength of current in the conductor or vice versa.

(ii)The direction of magnetic field around a straight current carrying conductor gets reversed if the direction of current through that conductor is reversed.

Answer 2

Answer:

(i) The strength of magnetic field around a straight current conductor increases on increasing the strength of current in the conductor or vice versa.

(ii)The direction of magnetic field around a straight current carrying conductor gets reversed if the direction of current through that conductor is reversed.
