    What happens when you have a magnetic halo with the
    length of 3/4 of an inch
    Width of 3/32 of an inch
    Height of 1in and 2/16 of an inch
    and u wire it with 125v fuse?

    dimension:

    -----------00l000000------
    -------080---l----08880---
    ----080------l------0880---
    ---080-------l-------0880--
    ----080------l-------0880---
    -----080-----l------0880--
    --------08---l----08880---
    -----------00l00000------


    0=Width
    8=Length
    l=Height

    I have no idea what a magnetic halo is. If it is some kind of electrical device, the physical dimensions won't tell you much about its electrical characteristics.

    A fuse has both a current rating and a voltage rating. The 125 volt rating tells you it can be used in a circuit up to a voltage of 125 volts.

    Your question is not making a lot of sense to me.

    Let me rephrase my question, normaly what happens when you wire a 125v fuse to a squared inch magnet?

    Are you talking about a permanent magnet? Why would you wire a permanent magnet? What is your power supply? What is the ampere rating of the fuse? There just isn't enough info here to give a sensible reply.

    Fuses are not rated in volts. They are rated in amps. The only bearing of voltage on the problem is that the fuse must be able to interrupt the rated amperage and not have the applied voltage create a permanent arc.

    Electromagnets get their magnetic field from the amperage flowing in a coil and the number of turns in the coil -- the important quantity is amp-turns. The fuse in the circuit, or lack of a fuse, has no impact on the magnetic field. It only serves to prevent overloading the wire and burning things up.

    I have no idea what a magnetic halo is.
