    How to connect to a 4 terminal inductor?

    Hello, The datasheet also tells not much. https://www.we-online.com/en/components/products/WE-HCFT?sq=7443783533330#7443783533330 The datasheets are under the specs buttons on the page. The datasheets of other coils show a different picture for connecting. There seem to be two edges connected...

    help with IR2110 chips

    Hello, You could also check the orientation of the magnets and coils using a gauss meter app on your phone: https://www.keuwl.com/GaussMeter/ Put a small current through the coil using a powersupply and a resistor, then measure the field using the app. Bertus
