Huh? No you can't due to leakage inductance.

Are you simply making a joke about permanent magnets?

How does leakage inductance relate to electrets?

In the exact same manner that leakage capacitance limits the field strength of permanent magnets--only more so by orders of magnitude.

This is, fundamentally, why electrostatic motors have not seen "power" applications. It's far easier to manufacture a high-tolerance lattice in metals than non-metals. https://ieeexplore.ieee.org/document/1038668
