Magnetic effect of current Worksheet-10
(i) the direction of deflection of the north pole of a compass needle kept at a given point near the conductor remains unaffected even when the terminals of the battery sending the current in the wire are interchanged.
(ii) For a given battery current, the degree of deflection of a N-pole decreases when the compass is kept at a point farther away from the conductor.
Which of these observations is correct and why ?
