(i) (a) A solenoid is a long coil containing a large number of close circular turns of insulated copper wire in the form of a cylinder.
(b) The magnetic field produced is similar to that produced by a bar magnet. Pattern of magnetic field lines due to a current carrying solenoid:
(ii) Since the current passes through the loop is clockwise, therefore, the front face of the loop will be the south pole and the back face, i.e., the face touching the table will be north pole. According to right-hand rule, the direction of magnetic field inside the loop will be pointing downward. In outside the loop, the direction of magnetic field will be upward.
