dannygrogan Posted February 28, 2016 Share Posted February 28, 2016 Hello everyone. I have just bought a small 12 volt electromagnet which i want to use to 'pull' an object suspended in liquid towards it to give the impression that the object is alive. I was just wondering what would be the best material to ebed inside the object(which will be made of silicon). The fist material which comes to mind is iron but im aware that there are other materials which are affected by a magnetic field. Is iron the most responsive to a magnetic field and so be the material to choose? I dont want anything too heavy either as this would impair the buoyancy and slow down the kind movement which i am looking for. Thanks very much for any possible replies, Dan.

DrP Posted March 1, 2016 Share Posted March 1, 2016 How about a very small neodymium magnet? They are light and powerful. A magnet will be more responsive than any metal. 1 Link to comment Share on other sites More sharing options...
Klaynos Posted March 1, 2016 Share Posted March 1, 2016 How about a very small neodymium magnet? They are light and powerful. A magnet will be more responsive than any metal. I'd agree with that. If you need it to not be a permanent magnet though I'd look at permalloy which is a nickel iron alloy. 1 Link to comment Share on other sites More sharing options...
