Eddy current braking apparatus includes a linear array (16, 18) of spaced apart permanent magnets (22) arranged to defining a slot therebetween and a diamagnetic or non-magnetic fin (42) disposed and sized to movement through the slot. A pivotal linkage (38) enables the magnets to move for a spaced apart first position with the fin to a second position in which the fin passes through the slot and a control mechanism selectively moves the magnets between the first and second positions. |
