Find the magnetic flux density when a flux of 28 units is enclosed in an area of 15cm2.
Correct answer: B. 186.67 units
- A. 178.33 units
- B. 186.67 units
- C. 192.77 units
- D. 200 units
Explanation
Total flux = B x A and to get B, divide total flux/area hence B = 28/0.15 = 186.67 units.

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.
