Hackaday Prize Entry: Visualizing Magnetic Fields
In 1820, Hans Christian Oersted discovered the needle of a compass would deflect when placed next to a wire carrying an electric current. It took 15 years for the first electric motor to be invented following this observation. Humans are dumb, but perhaps they wouldn’t be so oblivious to the basic facts of our reality if they could see magnetic fields. Or if they just had a 3D printer. For his Hackaday Prize entry, [Ted Yapo] is doing just this: adding a magnetic field scanner to a 3D printer, allowing for the visualization of magnetic fields in three dimensions.
