11C Lab 9 Changing magnetic field Before attempting the assignment read the description of Experiment 8 in the lab manual concentration on the theory. 11C Lab 9 Magnetic field and electromagnetic induction theory https:/youtu.be/syxoQ7d6Y1s 11C Lab 9 Magnetic field and electromagnetic induction experiment https://youtu.be/AUIBiTeuRnY Theory Magnetic flux Magnetic flux is a physical quantity that is proportional to the number of the magnetic field lines crossing a given area. Consider a small rectangular card of area A. The number of the magnetic field lines crossing the surface of the card depends on the orientation of the card. The number of lines is maximum when the card is perpendicular to the field lines, however, when the card is turned, the number of the field lines crossing it decreases. Magnetic flux is defined as following: OB = BIA =BA 1 = BA cos[ where B is the magnitude of the magnetic field, and O is the angle between the normal to the surface and the direction of the magnetic field. A , =A cos I Magnetic field lines of a bar magnet (a) and solenoid (b)N Faraday's law Faraday discovered two ways to produce an induced emf: First is to move a conductor in a magnetic field; N Second way does not involve movement of the conductor. Changing magnetic field induces an emf in a conductor even if the conductor is stationary. Magnitude of the induced emf around a loop is equal to the rate of change of the magnetic flux through the loop: 1= -00 B At B Electric current No movement Moving down Moving up Lentz's law The direction of the induced emfs and currents always oppose the change that produces them.Bmagnet Bmagnet S N S N Moving the magnet out of the coil. Moving the magnet in the coil. Magnetic flux increases. Magnetic flux decreases. Emf is induced. Emf is induced. Induced Bcoil is increasing and B coil Induced Bcoil is increasing and B coil is directed is directed opposite to B magnet in the same direction as B magnet Assignments Read the lab manual, view the videos with the theory and experiments. Analyze each experiment and prepare the report in the following format: Name/ Names: Date: Title Lab Objective: Write a short paragraph, in your own words, stating the objective of the laboratory. Equipment: Provide a sketch of the setup of the major pieces of equipment and their arrangement. Experimental Procedure: Summarize in a sentence or brief paragraph procedures, techniques, or methods used during the lab. Data & Analysis Describe the experimental setup and the measurement for each experiment. Include the electrical diagram for each experiment. Describe the experiment demonstrating the direction of the magnetic field inside the current-carrying coil. Illustrate the experiment. Using the right-hand rule, draw the direction of the electric current in the coil and corresponding direction of the magnetic field for two different current directions. Below is the example of how the illustration should look like for one of the possible directions of the current. Describe the experiment with two coils when the primary coil is connected to a battery through the switch. Explain all observations by making drawings and using Faraday's law, and Lenz's law, and the right-hand rule. Follow the rules: if the magnetic flux through the secondary coil changes the emf is generated in the secondary coil. Current starts to flow in the secondary coil. This current generates the magnetic field. The direction of the induced magnetic field in the secondary coil opposes the direction of the magnetic field in the primary coil if the magnetic flux increases. If the magnetic flux through the secondary coil decreases, then the induced magnetic field in thesecondary coil is in the same direction as in the primary coil. Illustrate the case of opening the switch separately from the case of closing the switch. Indicate the direction of the electric current and magnetic field in both coils, and indicate if the magnetic flux increases or decreases in each case. Copy the below templates in your report, and mark the direction of the currents in both coils and the directions of the primary and induced magnetic fields in them. Closing the switch Opening the switch Describe the experiment in which a bar magnet is moved in and out of the coil. Illustrate all four cases separately, following the rules described in the previous sections. Draw the direction of the current and magnetic field in the coil as the magnet moves in and out of the coil. S North pole in 4- - - - S N North pole out - - N S South pole inDescribe and analyze the experiment in which one of the coils is lifted with respect to another. .Follow the instructions in the video of the experiment). Describe the experiment on self-inductance. Include the schematics of the LR circuit. What signal is applied to the circuit/ wat is the peak-to-peak voltage, period, and'equency of the applied signal? How does the signal across the coil change with the change of the resistance of the box? Analyze the decay curve: plot the curve on the graph paper, and calculate the time constant om the graph. Also, measure the half-time t 1/5 and calculate from it. Calculate the inductance of the coil L from as explained in the lab manual.
