Hello
How to make buzzer how inductor work in buzzer it generate ac when I solder led it light on both side no positive negative it on off does it make ac oscillator
A 'buzzer' is historically a mechanical device, consisting of an electromagnet and a normally closed switch contact. When power is applied the electromagnet pulls a spring loaded metal lever towards itself, operating the switch and disconnecting the power - the cycle then repeats. Just the same as an electric bell.
A buzzer without a coil is most likely a piezo disc, and an electronic oscillator feeding it.
