Q. (a) Draw the pattern of magnetic field lines through and around a current carrying loop of wire. Mark
the direction of (1) electric current in loop (2) magnetic field lines.
(b) How would the strength of magnetic field due to current carrying loop be affected if
(i) radius of loop is reduced to half of the original value.
(ii) strength Of the current through the loop is doubled.
