(b) The magnetic field line is 

re17

(c ) 

  1. The magnetic lines are continuous.
  2. The magnetic lines start from north pole and ends at south pole.
  3. Two magnetic lines do not intersect each other.
  4. The relative strength state that closeness of field.

(d) Right hand thumb rule determines the direction of magnetic field associated with a current carrying conductor.

It states that imagine that you are holding a current-carrying straight conductor in your right hand such that the thumb points towards the direction of current.

Then your fingers will wrap around the conductor in the direction of the field lines of the magnetic field.
