    Physics - Permanent magnets

    I feel a sudden urge to muck around with industrial strength magnets; what type of permanent magnet will offer the greatest magnetic field / size [dont care bout weight] ratio?

    I think i know the answer to this question already, and thats the Neodymium Iron Boron type, but would like some verification. Thanks in advance.

    Hrm, now why would you be wanting super magnets? Your not going to try and rent a helocopter and fly over the IRS building with the magnet are you? CAUSE IT WAS MY IDEA AND IM GOING TO DO IT FIRST!
    Signature is optional, I didnt opt for one.

    No magnet is permanent, right?

    yes;


    A magnet is a metallic object capable of attracting iron and certain other metals and alloys. Around every magnet there is a region in which the force of the magnet exists. The region is called the magnetic field. The international unit of the magnetic field is the tesla (T). The strongest lab magnets are permanent, superconducting, and pulsed magnets. Permanent magnets retain their magnetism for a long time. The neodymium-iron-boron magnet is the strongest permanent magnet of our time, which can produce a field of about 0.1 T. Superconducting magnets are a type of electromagnet that produces a magnetic field from the flow electric current through a material with no resistance. A superconducting magnet can reach field strengths as high as 13.5 T. A pulse magnet provides very high magnetic field as high as 72 T.

    so your answer isulse magnet .

    720 times greater than NIB.

    u can bring jupiter to earth.

    cheers!

    72 Tesla pulse magnets....

    I doubt a mere science hobbyist like me can afford something with the word "pulse" in its name, nor have the power required to run it.

    >>The neodymium-iron-boron magnet is the strongest permanent magnet of our time
    Thanks, that answers my question.

    >>Your not going to try and rent a helocopter and fly over the IRS building with the magnet are you? CAUSE IT WAS MY IDEA AND IM GOING TO DO IT FIRST!
    What would that achieve?

    >>hey PT are you trying to make one onf those things that feep spinning all the time?

    To do that, ill need some sort of magnet that alternates field orientations; perhaps an electromagnet on AC. Too hardcore for me at this stage

    I disapprove. I feel a magnet sufficient to crash Jupiter into us would be much more powerful but lack the comprehension to say so without being a jackass!
