Answer 1

Answer:

Magnetic moment of two coils perpendicular to each other is given as

$M = \sqrt2 i \pi R^2$

Explanation:

Magnetic moment of a circular coil is given as

$M = iA$

$M = i\pi R^2$

now we know that the magnetic moment is a vector quantity and sum of magnetic moment of two coils is always given by vector sum of two coils

So we will have

$M = \vec M_1 + \vec M_2$

here we know that two coils are perpendicular to each other

so we will have

$M = \sqrt{M_1^2 + M_2^2}$

here we know that

$M_1 = M_2$

so we will have

$M = \sqrt2 i \pi R^2$
