The coil don't use attractive forces to push the pendulum. It uses repulsive forces. The switch is actuated when the pendulum has allready passed its minimum position. In order to accelerate it, it is necessary to push it away from the coil. Therefore the electro-magnet needs to get the same polarity like the polarity of the pendulum magnet.
shorter pendulum will run faster try using the electromagnet in the maximum H this way u can lower the energy consumption and less running time of the electromagnet did u measured the efficiency ?
poorly explained and filmed. you never metioned the spring potential energy which is what the kinetic energy of the magnet turns into as amplified by the electromagnet.
This is awesome and could be used as relay.
You could put two coils on this. One on each side of the swing to make it oscillate much faster
Simply and Clair.
Cool demonstation! Must try
This is really cool. Thank you.

A sort of DC motor that doesn't even need a reed switch? Clever! What is the current draw at let's say 5 volts?
Great job! What about the windings on the coil? How many? Did you do it yourself?
Could you add a capacitor to help boost the pulse?
Very cool. Could this be or is such a technique used for driving a clock and keeping time? For example, as a replacement for quartz crystal..
That's how atomic clocks work :)
Nice pendulum…… 👏👏👏 will the effect be the same if you reverse the polarity??

nice
Perpetual motion!
Indeed! It looks very cool as a desk toy and it consumes very little power, as little as 15 microwatts
