Question

draw the magnetic line of force in case of a circular coil of wire. how does the strength of the magnetic field at the center of the circular coil of a wire depends on (a) radius of the coil and (b) Numder of turn of wire in the coil

Answer 1

Answer:

As evident from the figure, the magnetic field lines will be less denser in the region near the circumference of the loop than at the center. Thus, the magnetic field will be stronger at the center of the loop than in the region near the circumference.
