Question

A wire of length l carries a current bent into various regular polygon shown below find magnetic moment in terms of length of the wire a equilateral triangle

Answer 1

Answer:

wire of length 'l' carries a current bent into various regular polygons shown below. Find magnetic moment in terms of length of the wire.

(a) Equilateral triangle (b) Square (c) Regular hexagon (c) Circular loop

Q.6. A current carrying wire of length 'l' is bent to form a circular coil of one turn. After that it is again bent to form a circular coil of two turns. Find ratio of magnetic moment of coils respectively
