Magnetic fields and moving electrons

[Glenn G]

Hi forum,
I have been thinking about the circular magnetic field pattern around a long straight current carrying wire and wondering about what the field pattern would be around an isolated electron moving straight in a vacuum? Somehow the magnetic field of all the individual electrons moving in a wire interact to produce the pattern recorded? (Suppose even vibrations of the ion lattice also adds to the overall effect?).
Regards,
Glenn.

have a read through this, it should answer most of your questions
