Hello,
Here is what I am comparing.
12v 500 Newtons Electromagnet with a 12V 2A power supply.
N45 150 Newtons 1.5" x 1/4" Neodymium Disc Magnet
When I compare the two magnet's strength, I find that the neodymium magnet is much much more powerful especially from a distance.
The electromagnet seems to work only at really close distances.
I initially thought this had something to do with the circuit I had with the electromagnet, but I removed basically everything and now just have the power supply plugged straight into the electromagnet. No difference.
Would anyone know why this would be? Why are the force ratings of the neodymium are 1/3 of the electromagnet, but yield maybe 4-5x the perceived strength, especially from a 2" distance?
Thank you,
