Is it possible to visualize magnetic flux lines
Correct answer: D. All cases are not possible
- A. yes directly we can see with eyes
- B. we need microscope
- C. we need telescope
- D. All cases are not possible
Explanation
This question tests electromagnetism, critical for medical students in physics (e.g., MRI applications). All cases are not possible is the closest correct answer, as magnetic flux lines require indirect visualization, not direct sight, microscopes, or telescopes. Other options misrepresent visualization methods, risking misunderstanding of magnetic fields.

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.
