Assertion
An electric bell is a mechanical bell that
functions by means of an electromagnet. When an electric current is applied, it produces a repetitive buzzing or clanging sound. Electric bells have been widely used at railroad crossings, in telephones, fire and burglar alarms, as school bells,
doorbells, and alarms in industrial
plants.
Reason
Electromagnetic force is the force of
attraction between the north and south
poles of magnets
