There is a point, P and a wire. P is at radial distance .0064 m from the wire's center. The wire has a resistivity of 1.62×10-8 Ω·m. Assume that the electric field driving the current is confined to the wire. Then determine the magnitude of the magnetic field B at point P due to the displacement current i in the wire at:
a)i=4A (.02 seconds)
b)i=8A (.04 seconds)
c)i=10A (.06 seconds)
Curent increases 1 A for every .005 seconds, then at .05 seconds currents holds steady at 10 A.
Help would be very much appreciated. I am not really looking for just the answer. Explainations and formulas please! Thanks!!
