Homework Help: Electromagnetism question

  1. Aug 11, 2004 #1
    An electric current passing through a coil of wire generated an electromagnetic effect.What effect does the number of turns of wire in a coil have on the size of the electromagnetic force?

    What hypothesis can u form and how do you use the domain theory to support this??

    Can you show us how far you've gotten on this one?

    There are two ways to do this. First, look at the formula for a solenoid and look at the part number of turns plays. Secondly, reason it out. What does each wire do? What happens when you add more?
