Embibe Experts Solutions for Chapter: Magnetism and Matter, Exercise 1: Exercise

For a sample of iron, the following relation holds-

$\mu \mathit{=}\left(\frac{0.4}{H}\mathit{+}12\times {10}^{-4}\right)\mathit{ }\mathrm{H}/\mathrm{m}$

Find the value of $H$ which produces a magnetic field of $1 \mathrm{T}$.

A magnetic field of $2\times {10}^3 \mathrm{A}/\mathrm{m}$ produces a field $8\mathrm{\pi } \mathrm{T}$ in a sample of iron rod. Find relative magnetic permeability of the sample.

A sample of volume $30 {\mathrm{cm}}^3$ is placed in magnetic field of $5 \mathrm{oersted}$. The magnetic moment induced is $6 \mathrm{A}/{\mathrm{m}}^2$. Find magnetic induction.
