A straight magnetic strip has a magnetic moment of $44 Am^{2}$ . If the strip is bent in a semicircular shape, its magnetic moment will be _______ $Am^{2}$ . (given $π = \frac{22}{7}$ )

Answer:

28.00

Solution:

Magnetic moment of straight wire $= mx ℓ = 44$ Magnetic moment of arc $= m \times 2 r = m \times \frac{2 ℓ}{π} = \frac{44 \times 2}{π} = \frac{88}{π} = 28$
