Thank you very much kind sir. I did the experiment to with a different magnet using 100 loop of cooper coil and I only got 10 microamps to show, sadly :( nor very spectacular like yours.

Can you please send me a link to the magnet you used in the electromagnetic induction video? I need to buy it for a science fair experiment.
