Correct answer: C. 4πx10-7T.m.A-1
- A. 10-7T.m.A-1
- B. 2πx10-7T.m.A-1
- C. 4πx10-7T.m.A-1
- D. 4πx107T.m.A-1
Explanation
The value of the permeability of free space, often denoted as μ₀ (mu naught), is approximately 4π × 10^(-7) T·m/A.The permeability of free space is a fundamental constant in physics that describes the behavior of magnetic fields in a vacuum or free space. It is related to the ability of a magnetic field to permeate through a given material.The value of μ₀ is defined in terms of other fundamental constants, such as the speed of light (c) and the permittivity of free space (ε₀). It is used in various equations and formulas in electromagnetism and electromagnetic theory to calculate magnetic fields, magnetic forces, and other related quantities.Note: In the International System of Units (SI), the permeability of free space is defined exactly as 4π × 10^(-7) T·m/A to eliminate any dependence on measurement uncertainties.

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.
