    Probably, but how appropriate is this project? Please embellish on your ideas otherwise I feel this may be straying a little out-of-bounds.

    It looks very nice, but I am a lost to see what you are trying to achieve, and sadly the link does not help any. The reason I am quizing this query in this way is that we have certain rules on the suitability of the requests and advice given here at AAC.

    If I'm interpreting Google results properly, ceramic magnets used in the motors of slot-cars are frequently re-magnetised (colloquially called "zapping") to maintain good performance. I don't know why rare earth magnets are not used, but it seems to have something to do with sportsmanship.

    I didn't dig up any info on how "zappers" work, but I suspect a nice strong electromagnet with small gap in the magnetic circuit would do the trick. "Capacitive discharge" makes me think one of these would be similar to a coin-shrinker or a coilgun.
