Lightest Strongest magnet I can buy

  1. May 14, 2015 #1
    Hi All,
    I am wanting to buy the lightest, strongest magnet I can. Can someone please direct me or give me guidance on this issue? I am requiring a magnetic field of >5000 surface gauss. Any links or direction would be terrific,

    Thanks in advance,
    Dale.

    Why not make a magnetic field by inducing a charge on some coils of wire, or would that be to heavy for what you want it for?

    Hi Raul,
    Thanks for your quick response. I require a permanent magnet. Yes the electromagnet would be far to heavy unfortunately. If I could get something like magnet paper with a strong magnetic field. This would be a very good solution.

    Regards,
    Dale.

    Seems lie your best bet would be a neodymium magnet, but the ratings of you desire/what you get, would depend on the geometry of the magnet.

    These might be your best bet, check what dimensions they have.

    Temperature range might matter.

    Hi Dale. Yes, I think one neodymium magnets can fit your need as of permanent magnets. However, you need to specify your exact working conditions as there will be limitation on working conditions of the magnets, especially for working temperature.
