Unit of relative permeability is
Correct answer: C. Dimensionless
- A. henry
- B. henry/m
- C. Dimensionless
- D. henry/sq. m
Explanation
Relative Permeability, μr, is given as the ratio of permeability of vacuum μ to the permeability of the medium μm.The formula is given by,μr= μ/μmAs it is a ratio of two similar quantities, it has no unit

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.
