A uniform conducting wire of length 18 a and resistance R is wound up as current carrying coil in the shape of a regular hexagon of sides a. If the coil is connected to a voltage source V 0 then the magnetic moment of coil is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
In the regular hexagon, if each arm length is a, then the number of turns in the given shape 
Now the area of given shape is
Now magnetic moment M = nIA
