{"product_id":"e-m-by-thomson-s-method","title":"E\/M BY THOMSON’s METHOD","description":"\u003cp\u003eIt is to measure e\/m of Electron by Thomson method Bar Magnet method. One Method to demonstrate modern physics in the controlled bending of beam of high speed electrons in a magnetic field. The actual measurement by student of the ration of the charge on the electron to its equally minute mass imparts a stimulating sense of achievement. E\/m apparatus has been perfected to the point where it is possible for this fundamentally important measurement to be carried out with good accuracy. Power supply: E.H.T. 800V D.C. for cathode voltage to C.R. tube. 50-0-50 volts D.C. with moving coil meters to measure the deflecting voltage either X or Y Plates. Cathode Ray Tube fitted on wooden frame with scale divided in centimeters. Deflecting magnetometer with permanent magnetic compass included. compass stand, a pair of Bar Magnet.\u003c\/p\u003e\n\u003ctable border=\"0\" cellpadding=\"0\" cellspacing=\"0\" width=\"278\" style=\"border-collapse: collapse; width: 208pt;\"\u003e\n\u003ccolgroup\u003e\n\u003ccol width=\"91\" style=\"width: 91px;\"\u003e \u003ccol width=\"187\" style=\"width: 185px;\"\u003e \u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr height=\"20\" style=\"height: 15.0pt;\"\u003e\n\u003ctd height=\"20\" class=\"xl65\" width=\"91\" style=\"height: 15.0pt; width: 68pt;\"\u003e\u003cstrong\u003eCategory No.\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"xl65\" width=\"187\" style=\"width: 140pt;\"\u003e\u003cstrong\u003eDescription\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"20\" style=\"height: 15.0pt;\"\u003e\n\u003ctd height=\"20\" class=\"xl65\" style=\"height: 15.0pt;\"\u003e101014\u003c\/td\u003e\n\u003ctd class=\"xl65\"\u003e\n\u003cspan style=\"mso-spacerun: yes;\"\u003e \u003c\/span\u003eE\/M by Thomson’s method\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eH108\u003c\/p\u003e","brand":"japson.com","offers":[{"title":"Default Title","offer_id":68054797090925,"sku":null,"price":0.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/8103\/1533\/files\/E-MBYTHOMSON_sMETHOD.jpg?v=1794483595","url":"https:\/\/japson.com\/de\/products\/e-m-by-thomson-s-method","provider":"japson.com","version":"1.0","type":"link"}
