Question

The units of magnetic permeability and magnetic flux density respectively are ________.

• A. F/m , Wb/m²
• B. H/m , Wb/m
• C. H/m , Tesla
• D. Wb·m , Tesla

Hint:

Remember: Magnetic permeability has the unit Henry per meter (H/m), and magnetic flux density is Tesla (T).

Answer 1

The Correct Option is C

Magnetic permeability \(\mu\) is the measure of how a material supports the formation of a magnetic field. It is defined by: \[ \mu = \frac{B}{H}, \text{ where } B \text{ is flux density, and } H \text{ is field intensity.} \] So, the SI unit of \(\mu\) is: \[ [\mu] = \frac{\text{Tesla}}{\text{A/m}} = \text{H/m} \] Magnetic flux density \(B\) is measured in Tesla (T). Final Answer: H/m , Tesla
