    Undergrad Speed of magnetic flux propagation?

    Thanks for the reply Baluncore, This at least answers my question as to whether to treat this more as a DC problem or AC. Although the math shows that it is still not full on AC at least for the coil resistance. At 110v/80A = 1.375 ohms, with the amperage still climbing versus the 2.355 AC ohms...

    Undergrad Speed of magnetic flux propagation?

    I have a case where I'm combining a N42 permanent magnet with two coils (20 AWG, 56 turns each, wired in parallel) to create flux transfer. Although model tools such as FEMM or SimScale model a static state of flux interaction, it seems clear based on experimentation that the flux interaction...
