The magnetic field on the axis of a circular loop of radius $100 cm$ carrying current $I = 2 A$ , at point $1 m$ away from the centre of the loop is given by:NEET 2022 (Phase 2)

Options:

Answer:

Solution:

As per question, we have; $B = B_{0} sin^{3} θ = \frac{μ _{0} I}{2 π} sin^{3} (4 5^{\circ}) = \frac{4 π \times 1 0 ^{- 7} \times 2}{2 \times 1} (\frac{1}{2})^{3} = 3.14 \times 1 0^{- 7} T$
