Physics, Astronomy & Cosmology / What is the best core material for a reciprocating electromagnet?
« on: 07/07/2014 20:59:06 »
I build reciprocating electromagnets using an iron core 1" to 1.25" in height and 5/16" to 3/8" diameter with a capacitor linking them, there's and armature bar and spring contact point system to make it reciprocate much like old doorbells. Is there a better core material I can use? And is there a better configuration for coils I can use to get the most out of this system where it will still function the way it's supposed to? I have included a pic so you can see what I'm using currently, must maintain a reasonable handheld weight, and withstand impact from the armature bar at the coil top unless there's a better way
