The value of permeability "μο" is
Correct answer: C. 4π × 10-7 Wb/Am
- A. 5π × 10-9 Wb/Am
- B. 8π × 10-10 Wbm/m
- C. 4π × 10-7 Wb/Am
- D. None of these
Explanation
The permeability of free space, denoted by μ₀, is a fundamental physical constant that represents the ability of a vacuum to support the formation of a magnetic field. Its value is approximately 4π × 10-7 Wb/Am

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.
