i have thought of that.. they would be perfect if i can make em fit right. but silver contact points are pretty cheap, an I've been looking into that a bit i wish i could show u a pic but I am trying to not give to much away before my patent.. if i could make an air coil the same strenght...

no they dont.. is there an easy way to tell how long a battery will power a continuous EM? because they make some nice batteries, i just wonder if it could run for up to 8hrs.. 1.5 amps, 3-10 DC volts (give or take.. room to fine tune its speed) output.. I have an DC regulated power supply

man i was trying to be secretive and u found me out.. hahah. but every time my girl uses it she gets shocked! haha.. but seriously thanks. that's good to know.. i figured on using brass or something. ill have to find some silver .. but wait. I am going to look into the vibrator deal a...

im using a manual switch to engage the piston. as soon as the magnet pulls the piston, it is pulled away from an electrical contact point shuting off the magnet. A spring returns the piston and repeats the process. I like the part about the piston becoming the core.. that could save space...

very informative.. thank you. but my real question is about the strenghts of a solid vs air core electromagnet. i would like to produce the same amount of power as an 8 layer coil (20 -24 gauge copper) 1 1/4" inch tall.. with a solid core. can an air core coil make as much power as a solid...

thanks, that's good to know.. i don't want heat to become an issue. but I am more concerned with power and the ability to work for hours

hello i need some help, i know very little about EM. i would greatly appreciate any advise u can lend me. i need to make an electromagnet but i am wondering how strong air cores can be? will an air core be able to work on and off continuously for hours at a very high rate of speed, it...
