I really need to make a very complicated electromagnet .. Is ther someone smart enough to help me ??

Hi, my name Peggy. Sorry, We're on holiday. Please come back in one week.

This site might help, I'm a little rusty, it's been a while since I constructed mine...

Heres a good site. DO you know AMperes Law? and understand magnetic permeability? The equations will help get started.
Flat shape with many turns of a coil and a mag permeability of over , say 200, which is magnetic iron.

One or the other. Not both. No such thing as free lunch. (To lift large weight requires energy. Energy comes from electricity supply.)

Instead of jacking up yer amps, I think your teacher wants you to figure out how you can "get a cheaper lunch". Its really not too difficult. Look at the field equations, it should hit you.
Also, looking at the magnetic permeability portion, have you looked into a nickel iron alloy for the core?. Look up the mag permeabi;lity of Mu- Metal.
We used to use it for old analog (fluxgate) magnetometers

How heavy? Weight required please. Also how far above is the electromagnet?



Give required amount of energy.

I just had a thought... this isn't a perpetual-motion machine, is it?
