"A short magnetic dipole has magnetic moment 1.5 A m^2. Calculate its magnetic field at a distance of 40 cm from the centre of magnetic dipole on (i) the axis (ii) the equatorial line (Given μ0 = 4 π x 10^-7 SI units)"
Added by Benzamin G.
Step 1
Given: m = 1.5 A m^2 r = 40 cm = 0.4 m μ0 = 4π x 10^-7 SI units Substituting the given values into the formula, we get: B = (4π x 10^-7 / 4π) * (2 * 1.5 / (0.4)^3) B = (10^-7) * (3 / 0.064) B = 4.6875 x 10^-6 T Show more…

"Find the magnetic field due to a dipole of magnetic moment 1.2 A-m2 at a point 1 m away from it in a direction making an angle of 60? with the dipole-axis."

The magnetic field at a distance $r$ from a magnetic dipole $\mu$ is $B=\mu_{0} \mu / 2 \pi r^{3}$. Show that the dipole-dipole interaction energy is too small to account for the ferromagnetism of iron at all but the lowest temperatures. Assume an effective magnetic dipole moment of $2.2 \mu_{\mathrm{B}}$ per atom.
