Will a circular loop of bigger radius produce higher magnetic field than a loop of smaller radius. If current flowing is same give reason.

Solution

No a circular loop of bigger radius will not produce higher Magnetic field than a loop of smaller radius. Since Magnetic field is inversely proportional to the radius of the loop. Therefore a circular loop of bigger radius produce lower Magnetic field than a loop of lower radius if the current flowing through both the loops is same
