Magnetically Driven Horizontal Pendulum

This video shows a curious pendulum that is driven by an electromagnet that interacts with a permanent magnet, and it is periodically kicked to maintain its motion.

Very nice! I`ll have to make it soon:) I really love your channel and your videos:) Thanks!

[@cphVlwYa]

There are so many factors in its movement that you could probably use it as a mechanical random number generator

[@ludicscience]

+Yextus Yes, I bet that the time series of the swing times is chaotic.

[@lopezstallon8449]

its a little bit difficult to balance the weight but its a cool project..... good for my lab decoration

[@davidmon7167]

Very interesting idea.

[@grain-diose]

This is not a pendulum, it is an electromagnetic interrupter.

[@michaelrtreat]

great explanation

[@ludicscience]

Thanks

[@kruppstahl1686]

wow really cool idea! i thought that a device like this could be used for DIY low power batteries. If you could combine a joulethief with this pendulum propaply it would move for a long time. Maybe you could use your LED flasher you recently built? I can also recommend using a larger electromagnet, with a higher resistance (thinner wire), so the voltage of the power source wont drop that much.

[@ludicscience]

+helut kuno Yes I also think that using very fine wire will give long run times with low power input. I will try that if I find the time!

[@raykent3211]

+Ludic Science Speaking of fine wire... I bought a japanese nodding toy (pendulum) because I was amazed to see it working under ordinary flourescent light in a shop basement. From a solar panel about 25mm by 8mm! Well, I had to take it apart, and broke it. The wire was thinner than a human hair and I'd guess about 10,000 turns on the coil. The design was moving magnet, stationary coil, contactless. Some clever stuff going on in the controller chip!

Yes, amazing technology for such a low price

Hello ludic, i am trying to make this pendulum, but i keep failing, are there any tips so i can make this pendulum work??

[@tessieangeles7405]

Good day sir can we produce an energy from magnet without electric ? Pls answer me thanks ...

[@fidelcatsro6948]

great video, alas if only we could do this with only repulsion of two magnets without the need for electricity...

[@hakeemnaa]

it is not a pendulum there is no constant oscillation and the frequency depends on the voltage which its tolerance will magnify overtime that why there is Quartz crystal oscillator inside electical watch and oscillation doesn't depend on the battery voltage there is tiny fork inside it to regulate the time

Thumbs up :) Alex

You are intelligent

[@mmuameal7802]

Many years ago I tried similar one 912 year's befor I think

[@minecrafter9099]

Hi can I use the ideas of your vids to create my own vids in Portuguese?

[@ludicscience]

+minecrafter9099 Yes of course, you can make your own versions, just dont copy the video or parts of it.

[@m7dtbh580]

Ludic science please help ! I want to make a voltage booster I tried the ones in your videos no one worked, and I tried with a relay when I connect it to a motor the voltage drops, please make a tutorial of a DC-DC transmeter

[@ludicscience]

+Herobrine GaMiNg what videos did you tried?

[@m7dtbh580]

+Ludic Science The "simple boost converter" and osaki ocillator I made sure used the same components with no differents

[@D_J_R_S]

Love it

[@ludicscience]

+DonJuanRicoSuave Thx

[@Kennynva]

I guess you could use a reed switch on the coil..so it would not have to touch..would this work???

[@ludicscience]

+Kennynva T. yes but then you have to find a way to transmit the electricity to the coil

[@Kennynva]

you make everything the same..as in the coil the same...and put the reed switch in the wire from the coil..

[@ludicscience]

+Kennynva T. It will not make any difference

[@ali.alabkari]

i like it ..

[@erwinputhoormanoj2965]

Bro Change the title, this is not a pendulum
