A square coil of side length 2 mm is placed in the x-y plane and in uniform magnetic field 0.1 T. Find total flux through the coil?
Correct answer: D. 0 Wb
- A. 1.6 Wb
- B. 0.16 Wb
- C. 16 Wb
- D. 0 Wb
Explanation
Magnetic flux=BA cos θ As the question states, it is placed in the 'x-y plane', implying that the angle between the magnetic field and the coil is 90 degrees. This would make the value of cos theta Zero. Hence the magnetic flux would also be zero.

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.
