    recharge or renew magnetic strength of magneto rotor

    I'm not uber-experienced, so take this with a grain of salt. According to the hysteresis curves (the full curve, not just the demagnetization quadrant), remagnetization is caused through the exposure to a large magnetic field, which gets the domains in the magnet material to line up and produce...

    magnetization

    MJR2, you say that the small n38 is charged all at once. That is not what I asked for. I asked if it is POSSIBLE to do it progressively or iteratively. I want to understand what can and cannot be done, not how difficult it would be, not what already is done. As for the large magnet, is there...

    magnetization

    The specific difficulties mentioned are why it would be advantageous (if possible) to build a solenoid of sufficient diameter and relatively short length, and progressively or iteratively magnetize such a large magnet with a matching graduated power demand. I don't need this info for an...

    magnetization

    I'll try to find the reference again, but my impression was that it was a single pole-pair neo. No mention was made of assembling pieces to build it. It seems like my question wasn't clear, so I'll try again. For reference sake, consider a single neo magnet 15 ft x 2 ft x 1 ft. Desired...

    magnetization

    Apparently magnetization methods are fairly secret since I never see any specifics in the books I've been reading. Can anyone tell me if a magnet material has to be magnetized all at once, or can it be done cumulatively? To put it in perspective, a 2x meter magnet was made for some particular...

    1020 cold rolled steel

    Can you please tell me the formula(s) and data sources to make such calculations? For the project I'm working on, variables such as magnet size, grade, and proximity to other flux sources aren't set yet, so I expect to need more calculations such as the permeance of the cap so I can figure a...

    1020 cold rolled steel

    Sorry about the delay, my password got messed up and they haven't responded to my request for help. Anyway The curve came from data in the 1018 thread you referred me to . I converted the units into CGS and graphed them in excel. That is why I wanted to double-check the values I got. As for...
