Question

In the given figure, what is the magnetic field induction at point O.

• A. $\frac {μ_oI}{4\pi R}$
• B. $\frac {μ_oI}{4R}+\frac {μ_oI}{2\pi R}$
• C. $\frac {μ_oI}{4R}+\frac {μ_oI}{4\pi R}$
• D. $\frac {μ_oI}{4R}-\frac {μ_oI}{4\pi R}$

Answer 1

Answer: (C)

$\frac {μ_oI}{4R}+\frac {μ_oI}{4\pi R}$

Answer 2

The correct option is (C): $\frac {μ_oI}{4R}+\frac {μ_oI}{4\pi R}$.
