Positive Biased Sine Waves- Log

[Jim Mac]

Hello,

I have been experimenting with positive biased sinewaves, creating induction without changing input current direction.  I think there is much to be discovered here.

One side weakens as the other strengthens, and it uses like polarities.  It simulates a permanent magnet in motion passing a coil. 



I will be updating as I continue

Great job on the sample! You now understand that the magnetic force must oppose and, specifically, the North poles must oppose each other. Yes, this distinction is important! My next step was to achieve a magnetic force of 1.8T on the north side of the electromagnet.

To accomplish this, you will need a reliable DC magnetic force meter. I have used several in the past, but I advise against purchasing them from eBay as they are often low quality. You can check the meter's accuracy by using a neodymium magnet with certification how many Teslas it should have
