Does this device give a magnetic field?

Hello,

It's a theoretical question. I take 2 electrostatic particules fixed in a circle. I turn the circle. Is there a magnetic field ? I suppose the angular velocity very high and I suppose the particules are fixed in the circle. The diameter of the circle is very small. I don't want the electromagnetic wave but the magnetic field at low frequency : magnetostatics.

Look at the Lienard Wiechert potentials. What do they say?

It's only for one particle ? And I'm looking for the magnetic field at low frequency not the electromagnetic wave.

Maxwells equations are linear. Just use superposition.

Sorry, but I don't undertand how to use your link to find the magnetostatic field, could you explain please ?

Calculate the field due to each charge, as described in the link. Then just add them together to get the total field.

Ok, and to have the magnetostatic field ?
