Question

An infinitely long straight conductor is bent into the shape as shown in the figure. It carries a current of I A and the radius of the loop is R metre. Then the magnetic induction at the centre due to circular part is-

• A. Zero
• B. tesla
• C. (p + 1) tesla
• D. (p – 1) tesla

Answer 1

Answer: (B)

tesla

Answer 2

Magnetic field due to circular part only = $\frac { \mu _ { 0 } \mathrm { I } } { 2 \mathrm { R } }$
