Question

4. If a current loop carrying a current I, with N turns and area enclosed by the current is A, then the magnetic dipole moment is given by
(A) m = A/NI
(B) m = NIA
(C) m= N/IA
(D) m = I/NA

Answer 1

Answer:

M=NIA.

Explanation:

From the question we get that the current carrying loop is carrying a current of I and with the number of turns as N. Hence, we get that the magnetic dipole will be directly proportional to the current in the given loop. Also, the magnetic dipole moment is directly proportional to the area of the closed current carrying loop.

So, if there is a current carrying loop of n number of turns so the magnetic dipole will be M=NIA.
