The flux is the region where the magnetic field _.
Correct answer: D. No change occurs
- A. Changes direction
- B. Changes strength
- C. Changes polarity
- D. No change occurs
Explanation
If magnetic flux in a region is constant i.e no change in flux linkage, it implies that the magnetic field present in the region is constant (no change in density or polarity). Hence, Option D is correct.

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.
