What is the trajectory a hypothetical stationary electron will make inside a static magnetic field?
It is known that an electron in a magnetic field will undergo gyromagnetic rotation of its spin magnetic dipole moment around the $B$ vector of the external magnetic field.
Also in addition to the ...

What is the physical explanation of why a stationary fermion is experiencing zero force from an external static magnetic field?
Since fermions like free electrons have an intrinsic spin magnetic dipole moment shouldn't they when subjected to an external static magnetic field experience a magnetic force even assuming they are ...

What would happen if you were able to shoot a oxygen plasma bead?
I was curious about the effects a bead of superheated oxygen (to the point of a plasma state) would have not the air and nearby spectators. It is my understanding that the temperature required to ...

Has magnetism been experimentally demonstrated at the quantum level?
I've learned that magnetic fields are generated by electric currents, and that electric current is the motion of electrons and stuff like that. Many textbooks also talk about "point charges" ...
