magnetic field lab report discussion

Magnets are used today to image parts of the body, to explore the mysteries of the human brain, and to store data for computers. PHYS 1493/1494/2699: Exp. As depicted in Figure 2, the North pole of the compass points towards the South magnetic pole of the Earth which is very close to the Earth’s geographic North Pole. Lab 7 - The Magnetic Field of a Long, Straight Wire Introduction Magnetic fields are produced by current-carrying conductors. ! Experiment 8 ~ Magnetic Field Induced by a Current-Carrying Wire Objective: In this experiment you will investigate the interaction between current and magnetic fields. Use a sketch as part of your explanation. It was ensured that … Webster Lab 5: Earth’s Magnetic Field 1 Abstract In this experiment, the Earth’s magnetic field is measured. Field lines form continuous, closed loops. Lab Magnetic Field in a Solenoid. This may … Nevertheless, working with these magnets can be dangerous. Objective The objective of this lab is to measure the magnitude of Earth’s magnetic field in the lab. Your value should, however, fall between 0.04 mT and 0.06 mT. The amount the rider has moved along the scale is directly proportional to the force felt by the conductor in the field. Apparatus: 2 round magnets, an electronic balance, meter ruler, retort stand Procedure: 1. The measure-ment involves combining the results of two separate experiments to obtain BH. Consult the TA, and make sure that you understand the cal-ibration. The magnetic field produced by the magnets in this setup is either pointing up, towards the coil, or down towards the benchtop. 3. Sample Lab Conclusion Paragraph. Whenever a current flows through a wire, a magnetic field is produced in the region around the wire. When an electric field exists in a metal, electric charges drift in the direction of the electric field. The strength of the magnetic field may be altered by varying the number of horseshoe magnets in the magnet assembly. ... Due to electric circuits in the laboratory, the presence of magnetic materials, etc., this total field for BE may or may not be the same as the Earth’s field (1 BE should be about 4.84×10−5 T or 0.0484 mT). Spin Coherence and Spin Control. Using a Helmholtz coil, a calibration constant is determined that is applied to deflection values obtained by a ballistic galvanometer. As with all physics laboratory experiments, one must be careful to use the appropriate units. 8, is the experimental value of Bh in agreement with the NGDC value? E05-1. Lab 5 - Force on a Wire Introduction A stationary or moving electric charge will experience a force when placed in an electric field.On the other hand, an electric charge has to be moving to experience a force due to a magnetic field.A current in a wire is due to moving electrons. Ronaldo Degazon Saturday 19/01/13 Physics Lab #18 Title: Aim: To investigate the effect of separation of magnets on the magnitude of magnetic force between them. Deflection of an Electron in a Magnetic Field Purpose In this lab, we use a Cathode Ray Tube (CRT) to measure the effects of an electric and magnetic field on the motion of a charged particle, in this case the electron. this laboratory, you will use a Hall probe to study the magnetic field distributions produced by both a Helmholtz coil and a solenoid. Before considering the effect of magnetic fields on conductors, we need some model to describe the flow of currents in response to electric fields. Print out a graph for your report. 5.2. The presence of these magnetic fields can be detected and measured by the force they exert on other magnetic materials and current-carrying conductors. Last modified on 17 June 2019 back to top What's the MagLab? Printer Friendly Version: In this lab we will investigate the magnetic field with a metal slinky with the use of a Hall probe. E. Use the "manual graph" file to plot a graph of B vs. x (magnetic field on the vertical axis. CSEC Physics Lab - Magnetic Force 1.
