Electromagnet

the magnetic force for consist inning give or get an electric shocking the loadstone of different place of the Electromagnet and loadstone can control of, but the loadstone then have no command over.
This characteristics of the Electromagnet has what function?It can make voice become big, take the telecommunication number the magnetic force of the right Electromagnet to proceed control,
Door bell that it can let the air in the speaker produce to vibrate, make out the voice, the Electromagnet can still let you make a noise
