Question

The magnetic susceptibility of iron is 5499. The relative permeability of iron will be ______.

Options

• 5500 × 10⁷

• 5500 × 10^-7

• 5500

• 5501

Answer 1

The magnetic susceptibility of iron is 5499. The relative permeability of iron will be 5500.

Explanation:

We know, Relative permeability μ_r = (1 + χ)

\[\therefore\] Susceptibility χ = μ_r - 1

5499 = μ_r - 1

μ_r = 5500
