Also if you glue magnets axially as shown in video they aren't going to repell each other. They will actually attract each other which is in fact a damping force. So it will bring swing to a steady state position sooner than without use of the magnets. U need to make sure they repell each other.
I've tried so many times, failed, so i made some adjustments to it, but sadly didn't work, hehe...the swing stopped.....maybe the magnet is not strong enough or its too strong....im not sure.....but thanks to Irfan for the ideas. 😀👍
