Question

A solenoid having \(400\text{ turns/metre}\) has a core of a material with relative permeability \(300\). If a current of \(0.5\text{ A}\) is passed through it, then the magnetisation of the core material is nearly

• A. \(6 \times 10^2\text{ A/m}\)
• B. \(6 \times 10^3\text{ A/m}\)
• C. \(6 \times 10^4\text{ A/m}\)
• D. \(6 \times 10^5\text{ A/m}\)

Hint:

Formula: $M = (\mu_r - 1)nI$

Answer 1
