The attraction capacity of an electromagnet will increase if the:
Correct answer: D. Flux density increases
- A. Core length increases
- B. Core area increases
- C. Flux density decreases
- D. Flux density increases
Explanation
Attraction capacity depends on the magnetic field strength which is called magnetic flux density. Therefore, if magnetic flux density increases, the attraction capacity also increases. 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.
