Surrounding A Current-Carrying Conductor Electromagnetics Experiment Demonstrator, Physics Oersted Experiment Instrument , Magnetic Field Around Current-Carrying Conductor Model(A)
WPPLKPJUM
➤Prove that there is a magnetic field around a current-carrying conductor; can verify the magnetic field of a straight-line current, etc ➤Place the experimental demonstrator on the table, place the large magnetic needle on the needle tip, and adjust the orientation of the base when the magnetic needle is stationary, making sure that the wire is parallel to the magnetic needle ➤Connect the DC 6V power supply, then you can see the magnetic needle swing, indicating that a magnetic field is generated around the current, and the right-hand rule can be used to determine the direction of the magnetic field ➤Change the direction of the current and look at the direction of the magnetic needle ➤Appropriate physical activities and research are not only fun, but can also enhance students' observation skills, stimulate questions, and connect the content of the book with real life
