If the coil is wound on an iron core, the flux through it will
Correct answer: D. increase
- A. decrease
- B. become zero
- C. remain the same
- D. increase
Explanation
When a coil is wound on an iron core, the presence of the iron core enhances the magnetic permeability of the medium. The increased permeability allows for more efficient concentration of magnetic flux within the core. Consequently, the flux through the coil increases compared to a scenario where the coil is not wound on an iron core.

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.
