How to Realize 1000 Tesla in a Laboratory

  1. Apr 18, 2003 #1
    If there's one thing Americans are good at, it's making bombs!

    As we all know, the US has spent a great deal of money investigating the science of Electro-Magnetic Pulse (EMP) warfare. As a result, researchers have developed destructive methods of creating extremely high magnetic fields, on the order of 1000 Tesla, for a few microseconds!

    What do we mean by destructive? We mean that there is so much current that passes through the magnetic field coil that it is vaporized after a single use! It should be noted that the most powerful superconducting, non-destructive magnets have field strengths an order of magnitude lower than that of a destructive magnet.

    So how do they do it? Well basically, they surround a conductor with plastic explosives, put it in a cryo-chamber, blast a sh:tload of current through it; and just before the coil has evaporated, they detonate the explosives -- causing the magnetic field lines to compress down to a very small cross-sectional area.

    In certain experiments, researchers have wanted to find the temperature dependence of a certain material in the presence of such extremely high magnetic fields. For each data point they take, they need an apparatus similar to that previously described. Each set of equipment costs the US tax payers about $5000... but we probably would have just used that money to buy more bombs anyway!
