Specification AgeRangeDescription : adult Brand : VERIMP BulletPoint1 : * Electromagnet Experimenter is used for group experiment equipment for junior high school physics students studying electromagnets BulletPoint2 : * During the experiment, a No. 1 battery was used to provide 1.5V power supply. BulletPoint3 : * There are two sets of coils, each set of coils has about 200 turns, and there is a tap in the middle. Each set of coils is equipped with 3 binding posts, which can be used interchangeably on U-shaped cores and cylindrical cores. BulletPoint4 : * The U-shaped iron core is equipped with an armature, and both the iron core and the armature have hooks for pulling experiments when they are pulled together. BulletPoint5 : * The U-shaped electromagnet, the single-pole switch, the battery box and the wire are assembled into a simple circuit, and the middle tap of the coil is used to connect the circuit twice to carry out the experiment. In the experiment, the pins are used to suck one after another, and the relationship between the number of coil turns and the magnetic force of the electromagnet is judged through the experiment.

During the experiment, after sucking a long string of pins, the pins fell down one by one, thereby verifying the relationship between the magnetic strength of the electromagnet and the coil current.Specifications:Size: 20*120*36mmMaterial: plastic box + metal partsNet weight about: 190gNote:Please allow little color difference due to different display or light environment.Please feel free to E-MAIL us if there are any problems and questions, we will try our best to MEET YOUR SATISFACTIONS WITHIN 24 HOURS.
