Product Name: Magnetic Lines Demo Board Size: 25cm/9.84in Instructions 1. Shake the demonstrator lightly to make the pointers, small needles in the holes or powders arranged irregularly. Objects appear magnetic field lines under the action of magnetic field. 2. When used for current and magnetic field teaching, connect the 6-9 volt power supply, and the irregularly arranged pointers, small needles or powder in the hole will obviously show the magnetic induction line. If the current direction is changed, the same effect can be obtained , which leads to the conclusion that there is a magnetic field around the current-carrying conductor.
Features
- This demonstrator is used for the teaching of physical magnetic fields in middle schools. There are three types: vertical, horizontal and three-dimensional.
- Bar magnets and hoof magnets can be used to demonstrate the formation of the surrounding magnetic induction lines and the formation of the magnetic induction lines when the magnetic poles are attracted or separated.
- Demonstrate the formation of magnetic flux lines in various spaces around the current magnetic field lines
- The demonstrator is made of transparent plastic, novel and beautiful, with obvious effect, which is intuitive and can be projected.
- We attach great importance to customer experience, if you have any questions, please contact us, we will reply you within 24 hours!
