Method for make simple scientific and technological gizmos
First of all, the tools we need to prepare are batteries, magnets and copper coils. Small magnets with the same poles (N pole and S pole) are attached to the positive and negative poles of the battery respectively. Then put the battery into the copper ring. At this time, you will find that the battery keeps shuttling in the copper wire ring.
Small magnets are the focus of this experiment. They not only generate a magnetic field, but also serve as conductors to connect the copper coil with the positive and negative electrodes of the battery. Even if current is generated in the copper coil, the electrified copper coil will generate a magnetic field according to the law of electromagnetic induction and the right-hand rule.
