About This

• 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.
• The presentation is intuitive, easy to operate, and highly visible.
• 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.
• Suitable for school teaching tools, learning displays and collectibles, will also be an important complement to laboratory supplies.
