    Question Electric Magnets

    Can anyone suggest a book or a web link that tells how to make and/or design electromagnets? I was hoping to find something that would give formulas etc. I tried the local library but had no luck.


    Thanks

    How big? How much weight does it have to hold? What kind of power source? Why re-invent the wheel? There's many sources for electro-magnets. (relays, solenoids, door holders, etc.)

    Here's one place:

    Check out the thread posted 03-13-2003 'What size magnet wire' for lots of discussion and relevant factors about electromagnets.
    I seldom do anything within the scope of logical reason and calculated cost/benefit, etc- I'm following my passion-
