{"product_id":"eddy-current-demonstrator-12-long-edycr1","title":"Eddy Current Demonstrator, 12\" Long - EDYCR1","description":"A simple but effective device for demonstrating Lenz's Law using eddy currents induced in the wall of a copper tube by a falling magnet. The demonstrator consists of a 12\" long copper tube and two apparently identical metal slugs with rubber end caps. One slug is plain steel and falls through the copper tube quickly. The other slug is a strong neodymium magnet that falls very slowly through the tube due to the braking effect of eddy currents. Includes activity guide.\u003cbr\u003e\u003cb\u003eAdditional Info:\u003c\/b\u003e A simple but effective device for demonstrating lenz's law using eddy currents induced in the wall of a copper tube by a falling magnet.
