PHY-132 Magnetic Fields- Joshua Manski Partner: Sandra Thoms Date: October 23 rd 2008 SLN# 82129, Thursday 12:00pm Brian Morrison Objectives : The purpose of this lab was to examine how a charged particle reacts inside a magnetic field. We studied how a particle will move in a circle whose size directly depends on the magnetic field and the energy of the particle. We practiced changing the magnetic field then the energy of the particle in order to change the particles path. We also calculated fundamental constants be analyzing our lab data. Experimental Procedure : The procedure for this lab was rather simple. Before we arrived to the laboratory the entire circuit that was needed was already connected. The circuit components needed to complete this lab are a Helmholtz coil to create the magnetic field, and an electron accelerator to propel

our particle. The electron accelerator is shown in Figure 1 while the Helmholtz coil circuit is shown in Figure 2. Figure 1. Electron emitter and accelerator Figure 2. Helmholtz coil circuit Since our circuits were already complete we started the experiment. First we turned off the light so that we could see the charged particle being emitted. Using flashlights we were able to see what we were doing. Initially all the power supplies were turned to zero. We then carefully turned the filament supply up to 4.2Amps and the accelerating anode voltage to 30V. At this

point we could see a blue beam that we being emitted out of the filament. We then turned on the coil circuit. Immediately we could see the beam deflect because of the magnetic field. To start taking data for this experiment we needed to set the accelerating voltage to a fixed value then vary the current controlling the magnetic field. We varied the magnetic field so it would cause the deflected beam to make a circle that touched some crossbar measurement points inside the gas filled tube. When the beam touched each of the five measurement points we
