Thanks mfb for the reply,... by a typical magnet, I mean a permanent, ceramic magnet in the 50-75 gauss range, not an electro-magnet. The experiment I have in mind is to brush the permanent magnet across an insulated conductor (steel or copper) with different orientations of the permanent...

Thanks for the reply truesearch... astute observation about the analog meter--probably right about that. And yes, I should probably be in the micro amp range to be sure to be sensitive enough. An oscillascope also would be great, but I do not have access to one, saving the data would also be...

Hi, I'd like to use a millivoltmeter to research voltages induced from a basic ceramic magnet brushing by a conductor. So, I need to buy a millivolt meter. What voltage ranges will be required, and what read-rate should the millivolt meter have (in order for it to register the voltage in a...
