Question

explain With a reason whether the field will Be strong at the Centre of current Carrying loop or near the circumference

Answer 1

For the magnetic field lines of a circular wire carrying a current, the lines of force near the wire are almost concentric circles. As be more towards the centre of the loop, the concentric circles become larger and larger. Near the centre of the loop, the arcs of these big circles appear as parallel straight lines. Thus the magnetic field is almost a uniform at the centre of the loop. By applying Right Hand Thumb Rule, we see that the magnetic field lines due to all the section of the wires are in the same direction with in the loop. That is the field is stronger at the centre of the loop.
