At this simple but ever-popular exhibit, black sand from nearby beaches make spiky patterns that reveal the invisible magnetic field between the poles of two giant magnets.
All motors operate for the same basic reason: When electricity flows through a wire and a magnet is nearby, the magnet exerts a force on the wire. Without either the magnet or the electricity, there is no "push" to make the motor turn. Turning the magnet over--reversing its magnetic field--reverses the "push" and causes an opposite rotation.
