unidentified electromagnetic shaker | Electronics Forums
05/09/2012· Hi everyone, I have been lent a small electromagnetic shaker, see attached pictures. The owner used it a long time ago (tentwenty years?) and cannot remember what make or model it is, only that it should vibrate a few mm. It has a metal mounting plate attached to it. It is about 70mm height, 65mm diameter with a 40mm stinger rod.
