Magnetism is related to:
Correct answer: C. Moving charges
- A. Stationary charges
- B. Stationary and moving charges
- C. Moving charges
- D. Law of motion
Explanation
Magnetism is intimately related to moving charges through the fundamental principles of electromagnetism. When electric charges, such as electrons or ions, are in motion, they generate a magnetic field around them. This magnetic field is responsible for the attractive or repulsive forces experienced by other moving charges in its vicinity.

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.
