GagalU Educational Science Model Physical Experiment Model Auster Experiment Verify The Existence of A Magnetic Field Around The Energized Conductor Teaching Instrument

I. Overview This instrument is designed according to the teaching needs of the new high school physics textbook. The demonstration proves that there is a magnetic field around the energized conductor. The presentation is intuitive, easy to operate, and highly visible. Operation method 1. Place the Oster experiment on the table, put the large magnetic needle on the tip of the needle, and adjust the orientation of the base when the magnetic finger is at rest, so that the wire is parallel to the magnetic needle. 2. Connect the DC 6V power supply. At this time, you can see the magnetic finger swing, indicating that a magnetic field is generated around the current, and the direction of the magnetic field can be determined by the right-hand rule. 3. Change the direction of the current and look at the pendulum orientation of the magnetic finger.

• This instrument demonstrates that there is a magnetic field around the energized conductor, and can verify the right-hand rule, the magnetic field of a linear current, etc.
• Place the Oster experiment on the table, place the large magnetic needle on the tip of the needle, and adjust the orientation of the base when the magnetic finger is stationary, making sure that the wire is parallel to the magnetic needle.
• Incredible physics lab equipment aids, or as a decoration in , make physics lab learning more effective.
• The presentation is intuitive, easy to operate, and highly visible.
• Suitable for school teaching tools, learning displays and collectibles, will also be an important complement to laboratory supplies.
