manipulation of magnetic feild's.
(OP)
Hello, I have a question to do with this topic and HOPEFULLY someone can help me out. I have been building an electro-magnet and been using core 15 and 13mm diameter in Iron. Length is 60mm and been trying all different types of AWG, Power supply 12V-DC, 60 AH, Windings currently unknown and have tried all different lengths ( can't understand how to work it out). I would like to use this without overheating- 24/7. My question is this- Is There a certain formula for electro magnet's or is alot of it guess work. Does anyone know anything that could be more useful? Would be most appreciated. NEOMAG, Thankyou





RE: manipulation of magnetic feild's.
A certain flux density you are shooting for.... maybe just close to saturation?
what is the significance of the "60 AH" rating of your power supply? Are you trying to conserve battery life, or you don't care about power consumption?
Is this 13-15mm diameter, 60mm long core shaped like a cylinder, or like a torus? (does the 60mm dimension follow a straight line or a circle?)

RE: manipulation of magnetic feild's.
The filed strength is amps x turns.
You have to know both numbers.
If you are going for high strength the best way is to us Cu foil, in your case 58mm wide, and thin insulation film 60mm wide.
You will run high current, low voltage in this coil.
We can talk about construction details later.
