>>11879396you know, wire wrapped around a magnet generates energy. in a guitar with steel strings the magnetic field changes with the string vibration and generates electric impulses that get converted in sound. in pic related, the wire is wrapped around steel screws and these screws are magnetized by one bar magnet.
i want to replace the bar magnet with disc magnets, one for each screw/slug. but the ones i have, would sit with the round part of them facing the screws.
