(A) Explain with the help of pattern of magnetic field lines the distribution of magnetic field due to a current carrying a circular loop.
(B) Why is it that the magnetic field of a current carrying coil having n turns, is 'n' times as larger as that produced by a single turn (loop) ?
Answers (1)
(A) Distribution of magnetic field due to a current carrying a circular loop is shown below-
At Every point of a current carrying circular loop, the concentric circles represent magnetic field around it which become larger as we move away from the wire.
At the center of the loop, these lines appear as straight lines.
(B) Magnetic field produced by a current carrying wire at a given point depends directly on the current passing through it. So if there is a circular coil having ‘n’ turns, the field produced is n times as large as that produced by a single turn. This is because the current in each circular turn has the same direction and the field due to each turn just adds up.
