See the production method below:
First of all, the tools we need to prepare include batteries, magnets and copper coils. Attach small magnets of the same polarity (both N or S) to the positive and negative terminals of the battery. Then put the prepared battery into the copper coil. At this time, you will find that the battery keeps shuttling in the copper coil.
Small magnets are the key point of this experiment. They not only generate a magnetic field, but also act as conductors, connecting the copper coil to the positive and negative poles of the battery. Even if a current is generated in the copper coil, at this time An energized copper coil generates a magnetic field according to the laws of electromagnetic induction and the right-hand rule.
