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.
