In science:

In the introductory section of Ref. Einstein discusses the phenomenon of electromagnetic induction in two reference frames: the first in which a magnet is in motion and a test charge is at rest, and the second in which the magnet is at rest and the test charge in motion.

As shown below, if he had, he might have obtained a very surprising result! In the case that the magnet is at rest and the test charge in motion, the latter moves in a inhomogeeous but static magnetic field and is sub jected a transverse Lorentz force which, in this case, explains the induction effect.
