Question

A suadent performs an experiment to study the magnetic effects of current around a current carrying
conductor. He reports that the direction of the north pole of a compass needle kept at a given point
near the conductor gets reversed when the terminals of the battery are interchanged.
a)What is the nature of magnetic field of a straight current carrying conductor?
b) Name and state a rule for finding the direction of this field
c) Give two factors on which magnitude of field depends



​

Answer 1

Answer:

A student performs an experiment to study the magnetic effect of current around a current carrying straight conductor. He reports that: ... Hence, the direction of deflection of N-pole of the compass needle cannot remain unaffected when the terminals of the battery sending current in the wire or conductor are interchanged.
