Caculate the Pull in LBS of Electromagnets

  1. Oct 13, 2008 #1
    I need to caculate the Pull in LBS of Electromagnets, i am missing some information regarding this & maybe some brain cells also.

    B (Flux Density)= Flux Lines/ Area

    Pull in LBS= B x A / 72,000,000

    Ok, how do i get B Flux Density in lines per sq/inch for the calculation.

    I guess it has to do with core permeability--i am using Steel
    Input voltage & Amps
    Number of turns on the Coils

    Some help would be greatly appreciated.

    Forgot to ask, should the core of a DC Electromagnet be Laminated?
