Find the magnetic induction at point O, if the current carrying wire is in the shape shown in the figure.

Options:

Answer:

Solution:

$B_{1} = 0,$

$B_{2} = \frac{μ_{0}}{4 π} \frac{I}{r} \times \frac{3 π}{2} ⊙$ ,

$B_{3} = \frac{μ_{0}}{4 π} \frac{I}{r} ⊙$

$B = B_{2} + B_{3} = \frac{μ_{0} I}{4 π r} [\frac{3 π}{2} + 1] ⊙$
