Specification Brand : Dntum BulletPoint1 : Purpose: Demonstrate the phenomenon that direct current passes through the wire to generate a magnetic field around it, and the relationship between the direction of the magnetic field and the direction of the current. BulletPoint2 : Structure: The current magnetic field demonstrator is composed of three pieces of linear current magnetic field, circular current magnetic field, and solenoid magnetic field demonstrator, all of which use multi-turn coils instead of single-stranded wires to increase the magnetic induction intensity and enhance the demonstration effect. BulletPoint3 : This instrument is made of transparent materials. Avoid surface friction and maintain its transparency. BulletPoint4 : During the demonstration, after the magnetic induction line is formed, the power supply should be cut off to avoid excessive temperature and damage to the instrument. BulletPoint5 : After the experiment, the iron powder should be cleaned with a brush.
