Single Choice

A wire carrying $$I$$ is shaped as shown. Section $$AB$$ is a quarter circle of radius $$r$$. The magnetic field at $$C$$ is directed:

AAlong the bisector of the angle $$ACB$$, away from $$AB$$
BAlong the bisector of the angle $$ACB$$, towards $$AB$$
CPerpendicular to the plane of the paper directed into the paper
Correct Answer
DAt an angle $$\pi /4$$ to the plane of the paper

Solution

Use Right hand palm rule or Maxwell?s Cork screw rule.
Perpendicular to the plane of the paper directed into the paper.
Hence,
Option $$C$$ is correct answer.
