Study the phenomenon of electromagnetic induction: connect the two ends of the secondary coil B to the two terminals of the ammeter with wires;When using one end of the bar magnet to quickly insert (or withdraw) the secondary coil, the pointers of the galvanometer are all deflected, indicating that there is an induced current in the secondary coil at this time. This phenomenon is called electromagnetic induction. On the contrary, if
