What is the difference between Gauss’s law in electrostatics and Gauss’s law in magnetism ?
Magnetic intensity for an axial point due to a short bar magnet of magnetic moment $M$ is given by
Magnetic lines of force due to a bar magnet do not intersect because
The magnetic moment of a magnet of length $10\, cm$ and pole strength $ 4.0\, Am$ will be......$A{m^2}$
The earth’s magnetic field at the equator is approximately $0.4 \;G$. Estimate the earth’s dipole moment.
