Abstract
Eddy current braking apparatus includes a linear array of spaced apart permanent magnets arranged for defining a slot therebetween. A diamagnetic or non-magnetic fin is disposed and sized for movement through the slot. A pivotal linkage enables the magnets to move with respect to the fin from a spaced apart first position to a second position in which the fin passes through the slot. A control mechanism selectively moves the magnets between the first and second positions.
