Red electrical insulation varnish, and then a layer of masking tape. Heat shrink would work as well, the point being that you do not want any contact of your magnet wire with the core. I don't know exactly what stilted coils are. I have seen coils on e-bay that were called "stilted" it looks to...

The round stock is the right grade, but galvanized which is no good for my application. 1018 is what I use for all my dimensions already. I would be happy w/ 5/16 rod & 5/16x3/8rect in 1010 or lower. I use this material for elctromagnets and armatures. Not solenoids, but a soild core...

I've dealt with a few local machine shops as well, seeing if they had access to the grades I'am looking for with no luck. The machining I do myself. I don't need specific parts machined. I just need the dimensions that I stated in any particular length. Usally I buy my other metals by the ft. In...

The corrosion is not an issue, I've tried all the sites you listed with no luck, I'am looking for 5/16" rod and 5/16"x3/8" rect. As well as 3/16"x3" rect. and 1/4"x3/4" rect. I live in Wilmington N.C I've tried local steel suppliers and they can't help me, and keep sending me around in circles...

anyone know of a supplier of c.r low carbon steel ie. 1010, 1008, 1002 I can't find a supplier, any info would be appreciated, thanks

hey, I build one off tattoo machines. As far as coils go, For the cores use the the lowest carbon content steel available. 1018 is standard but if you can find it 1008 or 1002 is best inch and a quarter long. Use 24 awg wire, insulate the cores with varnish & tape and wind your wire as evenly...

magnet wire for basic solid core electromagnets. I don't need anything specific just ordinary magnet wire. I have been buying magnet wire from parawire.com, and really had not considered the "quality" of their product it performs fine, just curious if there was a reputable brand or supplier, Thanks.

which brand magnet wire is considered the highest quality, Belden seems to come recommended, any others would be appreciated

I think I understand hysteresis, This is in relation to a tatoo machine, I posted a question which no one responded too earlier. I figured hysteresis would cause somebody to give some info. any way this is a "doorbell" circuit two coils a switch/contact with a capacitor. or an oscillating...

could someone explain in layman's terms hysteresis, and why this would contribute to heat in electromagnets

I will keep this brief a tattoo machine is basically an old fashioned doorbell. to coils wired together with a resistance of 2 ohms, generally a 47uf 50v electrolytic axial capactior. the contact is a spring and copper screw. the circuit opens and closes rapidly, 105hz to 145hz. my question is...
