Give the uses of electromagnets.
(N/A) Electromagnets are used in various devices due to their ability to turn magnetism on and off. Common uses include:
$1$. Electric bells: Used to create the ringing sound.
$2$. Loudspeakers: Used to convert electrical signals into sound waves.
$3$. Telephones: Used in the diaphragms to convert electrical signals into sound.
$4$. Cranes: Used in industrial settings to lift and move heavy magnetic materials like iron and steel.
