Electromagnet which produces varying magnetic flux

  1. Jan 29, 2016 #1
    I want to make an electromagnet but it should
    Produce magnetic flux which changes with time.
    What material wire would be the best to make make windings?

    The usual choice is copper.

    The way to make the flux change with time is to make the current at the power supply change with time. The magnet coil's material - usually copper - shouldn't enter into it.
