Design of an Electromagnet

  1. Jan 25, 2012 #1

    I am trying to design an electromagnet. I am utilising the lorentz force equation to develop the force. i.e. F= BIL.

    The problem is I can't increase value of B beyond 1 tesla as the core saturates. Also high current is not feasible.

    Can any one suggest how to increase the value of flux density (B). Is there some other material present that can give flux density more than 1T.

    Anticipating a positive reply.

    Thanks is advance.

    Plain old iron should go up to 1.5 to 2 tesla.

    You don't say what it's for so I don't know if this is at all applicable but you can get NdFeB permanent magnets quite cheaply nowadays. They go up to over 1.5T.
