1. A generator comprising:
a first shielding disk and a second shielding disk separated along an axis by a space and configured to rotate around the axis, each shielding disk having alternating regions of magnetic shielding and non-shielding arranged a common radial distance from the axis, each region of magnetic shielding on the first shielding disk being azimuthally-aligned with a region of non-shielding on the second shielding disk
a pair of magnets disposed in a stationary position with respect to the axis, the pair of magnets comprising:
a first magnet located axially above the first shielding disk with a first pole of the first magnet facing the first shielding disk; and
a second magnet located axially below the second shielding disk at the same azimuthal position as the first magnet with a second pole of the second magnet facing the second shielding disk; and
a conductive wire arranged in the space between the first shielding disk and the second shielding disk, the conductive wire comprising a coil with a plurality of windings extending back and forth across the axis.
