Instead, the coil is pulled through the external magnetic field, which induces a voltage across it.

Most materials, including milk and water, are diamagnetic, which means they are repelled by external magnetic fields though this phenomenon is far too subtle to be observed in normal circumstances.

ECONOMIST: Monitor

The coil is suspended in an external magnetic field and the current running through it adjusted so that the attraction between the two magnets balances the gravitational force on the suspended mass.
