It consists of an iron core, a solenoid coil and an armature. The iron core is attached to the end of the air track where it provides a mount for the coil. The glider is connected to the coil via the armature and catapult. When the current is interrupted, the tensed rubber band imparts energy to the glider. A switch box (1019301) is used to activate the system.","brand":"3B Scientific","offers":[{"title":"Default Title","offer_id":49419147378965,"sku":"3BS1019300","price":376.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/U20611_01_1200_1200_Electromagnetic-Launch-Apparatus-recommended-accessory-air-track.jpg?v=1761030021","url":"https:\/\/unitedsupplycorp.com\/products\/electromagnetic-launch-apparatus-recommended-accessory-air-track","provider":"United Supply Corp.","version":"1.0","type":"link"}
