A rectangular loop of wire is placed midway between two long straight parallel conductors as shown. The conductors carry currents "I1" and "I2", as indicated. If "I1" is increasing and "I2" is constant, then the induced current in the loop is:
Correct answer: B. Counter clockwise
- A. Zero
- B. Counter clockwise
- C. Clockwise
- D. Depends on I1 or I2
Explanation
The explanation is: As I2 is constant, so, there will be no induction due to I2 in the loop. The current will be induced in the loop only due to increase in I1 (increasing magnetic flux). So, by Lenz's law the direction of induced current is anticlockwise.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
