Write the Gauss’s law in equation form for electrostatics and magnetism. What is the difference between them ?
Two identical short bar magnets, each having magnetic moment $M$ are placed a distance of $2d$ apart with axes perpendicular to each other in a horizontal plane. The magnetic induction at a point midway between them is
The $ S.I.$ unit of magnetic permeability is
