This one has DC collection on the front and AC collection on the back of the same armature, so a class compares two traces from one turn of the handle. The difference between a split ring and slip rings stops being a diagram.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIt runs the other way too.\u003c\/strong\u003e Feed current in and the same machine demonstrates an electromagnetic motor - which is the point students most often miss, that a motor and a generator are the same machine used in opposite directions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHand driven, so no batteries and no power point.\u003c\/strong\u003e The mechanical energy comes from a student's arm, which also makes the energy conversion obvious: turning gets harder as more current is drawn, and that is a lesson you cannot get from a battery.\u003c\/p\u003e\u003cp\u003eDesigned for low-current experiments. Connect it to a lamp, a galvanometer or an oscilloscope - none of which are included.\u003c\/p\u003e","brand":"MTA Essentials","offers":[{"title":"Default Title","offer_id":53793090503019,"sku":"EVEIS1245N8","price":184.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/2795\/8891\/files\/eis1245n8_ac-dc-motor-generator-demo_v1_1.webp?v=1788359180","url":"https:\/\/megaofficesupplies.com.au\/products\/ac-dc-motor-generator-demonstration-model","provider":"Mega Office Supplies","version":"1.0","type":"link"}
