Summary
In North Carolina, filmmaker and experimenter Joey Shanks demonstrates magnetic putty engulfing nearby objects and magnets. The putty contains many particles of iron oxide (magnetite). Their electrons produce tiny magnetic fields, but these fields are usually oriented randomly, so the putty has no strong overall magnetic field.
When a powerful neodymium magnet is brought close, the particles align with its field, drawing the putty toward the magnet until it surrounds it.
Shanks filmed the effect using time-lapse photography, taking one picture per second. One demonstration took about ten minutes to complete. He also describes experimenting with different lighting and materials to create visual effects.
Demonstration Method
- Use magnetic putty containing iron oxide particles.
- Bring a strong neodymium magnet near the putty.
- Observe as the putty moves toward and envelops the magnet.
- Record the process with time-lapse photography.
