Magnetism: the forces around us

Magnetism is part of our everyday lives, but the variety of ways in which
it is used is commonly overlooked.
While fridge magnets holding mementos and reminders in place are obvious examples, less apparent are the magnets or electromagnets in earphones, loudspeakers, doorbells, security systems and induction cookers. Our household appliances contain electric motors that rely on electromagnetism, which is also used by electric generators to produce electricity. Magnetism is even used
to store data on hard disks in our computers and on the magnetic stripe on our bank cards.
