#$&* course PHY 242 3/27 11:40 In this lab we took an amp meter, a volt meter, two AA batteries and a 50 cm NiCh wire. We then made a series with the batteries first then the amp meter then the volt meter then the NiCh wire then back to the battery. Our volt meter was reading 2.4 volts but the batteries added up to 3 volts so there was resistance in the NiCh. The surface area of the NiCh is 1x10^-3 m^2. Then we ran the wire through a pvc cylinder so then we wanted to find the flux of the wire on the cylinder so to find the flux we did the following, flux= (4*pi*(charge density of wire*length of wire))/( 2*pi*(radius of tube*length of tube).
