Copper wire is wound around a steel bar FT. Current is allowed to pass through the coil for some time and then the bar is removed.
Trace two magnetic lines of force around FT clearly indicating the direction

Answer
Solution diagram
Exam answer
Draw two closed magnetic field lines outside the bar from F (N) to T (S), with arrows from N to S.
Explanation
Inside the magnet the lines return from S to N.

The diagram below shows the top view of the Wire A shown by a cross (X), carrying current into the plane of the paper. Which of the compasses is correctly aligned with the magnetic field produced by the current carrying wire?
(a) Only 1 is aligned
(b) Only 2 is aligned
(c) Both 1 and 2 are aligned
(d) Both 1 and 2 are not aligned2026intensifies the magnetic field.2026maintains electrical contact between the rotating parts and the external circuit.2026in the direction of the motion of the magnet?2026in the opposite direction of the motion of the magnet?2026The following figure shows a small bar magnet falling freely through a copper ring. For the observer at A, the direction of the induced current will be :
(a) clockwise when magnet is above and below the ring
(b) anticlockwise when magnet is above and below the ring
(c) anticlockwise when magnet is above the ring and clockwise when the magnet is below the ring
(d) clockwise when magnet is above the ring and anticlockwise when the magnet is below the ring2025
