Thermal Expansion

  1. Jan 23, 2007 #1
    Hi guys,

    I need to find out what current i need to expand different type of coils. eg iron, aluminium, copper, etc. Is there a website that can give me this information? I tried searching but no luck.

    Thx

    Try searching for the resistivity of those metals. A non ideal inductor (coil) can be modeled as an ideal inductor (zero resistance) in series with a resistor equal in value to the resistance of the length of wire.
