Question

Consider the situation shown in figure. If the current $I$ in the long straight wire $\text{xy}$ is increased at a steady rate the induced current in loop $\text{A}$ and $\text{B}$ will be

• A. Clockwise in $\text{A}$ and anticlockwise in $\text{B}$
• B. Anticlockwise in $\text{A}$ and clockwise in $\text{B}$
• C. Clockwise in both $\text{A}$ and $\text{B}$
• D. Anticlockwise in both $\text{A}$ and $\text{B}$

Answer 1

Answer: (A)

Magnetic field in $\text{A}$ will be outward and in $\text{B}$ it will be inward, given by right hand thumb rule. So to oppose increase in magnetic field in loop in respective direction current induced will be clockwise and anticlockwise respectively.
