Understanding Spin Magnetic Field and its Direction in Relation to Charge Spin

[M.Kalai vanan]

When a electron or any charge spins what is the direction of the magnetic field generated by its spin?
what is the rule connecting the direction of spin of the charge and direction of magnetic field

 

[Simon Bridge]

It's the same rule as for rotating charge distributions.
For a positive charge, the magnetic moment points in the direction of the spin, and it's the other way for negative charges.
