Science Buddies: "Ask an Expert"

Hello, I am doing a project where I move a Neodymium magnet closer and farther to a circuit and see how it affects the voltage. Is there any suggestions you have to set up the circuit? Thanks!

Hi - we have several projects about generating electricity with magnets that you may find useful:

Note that the magnet needs to be moving to generate a voltage. Holding the magnet still at a fixed distance will not produce any voltage. You can read more about the physics in the background sections of the projects I linked above.

Thanks!
