PHXII04:MOVING CHARGES AND MAGNETISM

362613 A direct current I flows a long the length of an infinitely long straight thin walled pipe, then the magnetic field is

1 Uniform throughout the pipe but not zero
2 Zero only along the axis of the pipe
3 Zero at any point inside the pipe
4 Maximum at th centre and minimum at the edges.

362614 A square conducting loop of side length \(L\) carries a current \(I\). The magnetic field at the centre of the loop is

1 Independent of \(L\)
2 Proportional to \({L^2}\)
3 Inversely proportional to \(L\)
4 Linearly proportional to \(L\)
