... when all the electrons spin in the same direction. When you bring two magnets together they exert a push or pull called a magnetic force. This force results from spinning electric charges of electrons in the magnet. The force can either push magnets apart, or pull them together. Magnetic force is on ...

... Replacing B with ∇ × A in the differential form of Ampère’s Law: ∇ × B = ∇ × ∇ × A = µ0 J Using the identity “curl curl = grad div - delsquared”: ∇2 A − ∇(∇.A) = −µ0 J The choice of ∇.A = 0 is made for static fields This is known as the Coulomb gauge It leads to Poisson’s equation for A: ∇2 A = −µ0 ...

... You may see a small reading from the probe even when it is not next to a magnetic field. This is due both to local conditions and variations between data loggers. It is quite usual and can normally be ignored where trends of change and field strength are generally more important than accuracy. Some so ...
