The magnetic field is parallel to a surface, then the magnetic flux through the surface is _.
Correct answer: A. Zero
- A. Zero
- B. Small but not zero
- C. Infinite
- D. Large but not infinite
Explanation
Option A is correct since if the surface is parallel to the field, then no field lines will cross that surface, and the flux through that surface is zero.

About Magnetic Flux
Magnetic flux measures the magnetic field passing through a surface, calculated for a uniform field as Φ = BA cos θ, where θ is the angle between the field and the surface normal. Questions involve area, field strength and orientation, the weber as its unit, and the distinction between flux and magnetic field.
