Is it possible to cause frame dragging in Spacetime with a rotating electromagnetic field?

Frame dragging involves a rotating massive object warping Spacetime, and I was wondering if electron fields rotating could cause small frame dragging effects

    No. Gravity is a deformation of spàcetime. But electromagnetism is not. No Relativity effects can be produced by electromagnetism.

    Update : @jeffdanielk - absolutely incorrect. Look up the stress-energy tensor for electromagnetic fields. Every bit a source of gravity as a matter stress-energy tensor.

    Yes. Any angular momentum will generate frame dragging effects, albeit incredibly small for electromagnetic fields.

    As an extreme example, there is an exact solution of Einstein’s field equation for rotating charged black holes (Kerr-Newman metric). It has an ergosphere (the point where everything - even light - is forced to co-rotate with the black hole due to frame dragging) and that ergosphere depends on the electric charge.

    So, yes, but immeasurably small frame dragging except for extreme cases.

    It will be hard to find, considering uncertainty principle.
