Divergence of magnetic field b is always
While a more general proof may be possible, three specific cases are considered here. The first case is a magnetic dipole of constant magnitude that has a fast (fixed) orientation. The second and third cases are magnetic dipoles where the orientation changes to remain aligned either parallel or antiparallel to the field lines of the external magnetic field. In paramagnetic and diamagnetic materials the dipoles are aligned parallel and antiparallel to the field lines, respectiv… WebSep 12, 2024 · The component of the velocity perpendicular to the magnetic field produces a magnetic force perpendicular to both this velocity and the field: (11.4.4) v p e r p = v sin θ (11.4.5) v p a r a = v cos …

WebMar 3, 2016 · Interpret a vector field as representing a fluid flow. The divergence is an operator, which takes in the vector-valued function defining this vector field, and outputs a scalar-valued function measuring the change in density of the fluid at each point.

The fact that the magnetic field is divergence-free, is a consequence of observations, not a mathematical fact. Basically, the divergence of a field (like the electric field) is equal t...
In physics, Gauss's law for magnetism is one of the four Maxwell's equations that underlie classical electrodynamics. It states that the magnetic field B has divergence equal to zero, in other words, that it is a solenoidal vector field. It is equivalent to the statement that magnetic monopoles do not exist.
