Calculating magnetic pull force with air gap distance and steel thickness

Hi everyone

Looking for a simple and easy way to calculate the magnetic pull force either in newtons or pounds between N35 magnet and a steel plate where the gap between the magnet and steel plate is X and the steel plate thickness is Y.

Thank you...

If anyone knows of a built in calculator or a simple way to calculate this.

Pls let me know.

B

"Pull force" would be in newtons, or pounds force. Gauss and Tesla are units of magnetic flux, not force.

Here's a link to a calculator that may be helpful. Note that the size and shape of the magnet are important characteristics, as well as distance to the steel plate: https://www.kjmagnetics.com/calculator.asp

Thank u chipB. I don't know what gone into me when I wrote the question ... I have corrected it now.

I have tried that calculator but it only provide an answer to either a gap or a steel thickness . I am looking for both gap and steel thickness at the same time .

Any idea of a simple way to calculate the magnetic pull force either in newtons or pounds between N35 magnet and a steel plate where the gap between a magnet AND steel plate is X AND the steel plate thickness is Y. .????
