Simple electric motor using a single neodymium magnet sphere 19 mm, a coil iron less, a small solar panel, rectifier (optional ) . A pulse motor using a single neodymium sphere VIDEO : <a target="_blank" rel="noopener noreferrer" href="https://www.youtube.com/watch?v=SSwhofB7v5oA">https://www.youtube.com/watch?v=SSwhofB7v5oA</a> pulsed motor uses short pulses of current to drive the motor, making it spin.<br>The neodymium magnet sphere is acting as a flywheel.<br>The pulse motor is one of the simplest motors and works very well under low voltages.<br>When magnet gets close to the reed switch, the two contacts inside the glass tube get magnetized and touch each other.<br> The coil iron &#x2013; less pushes magnet away and making it spin.<br>The rotor continues to spin due to inertia until the magnetic field gets in working range of the reed switch again.
