Phys 2240 lab07/31/2017Experiment 9Magnetic Field in a Current Carrying CoilLeesa Jorgenson
IntroductionIn this experiment, our objective was to measure the magnetic field when we push the probe through a coil comparing changes in axial and radial magnetic field components as the position of a magnetic field sensor. It is recorded by a string attached to the magnetic field sensor that goes over the rotary motion sensor pulley. We want to verify that our theoretical hypothesis matches with our experiment. TheoryThe magnetic field sensor can record the axial and radial components of the magnetic field. It will record the magnitude of each component as well it will detect the direction of each field component. We can measure the field in a single coil by using the equation 1: B=(µoNIR2) / (2(x2+R2)3/2), B=the field, R=radius, N= turns, and µo= 4π x 10-7 T. The long solenoid, the equation 2: B = µonI. Experimental Procedure In the experiment, we start with the power off and setup the sensor is in the center of the coil.
