Write an essay on the daily life uses of magnets.

Debit, credit and ATM cards have a magnetic strip on one of their sides. This strip encrypts the information of the user’s financial institution and links it with their account.
Old televisions (CRT model)) and old large computer monitors contain a cathode ray tube that works on an electromagnet to direct electrons to the screen.

VHS tapes consist of a roll of magnetic tape. The data that forms the sound and video is embedded in the magnetic overlay on the tape.

Most of the microphones and speakers use a current-carrying coil and a permanent magnet to transform the signal or electric energy into mechanical energy (motion that generates the sound). The coil is enveloped around a reel connected to the speaker cone, and bears the signal as a varying current that interacts with the permanent magnet’s field.

Several types of electric motors depend upon a combination of a permanent magnet and an electromagnet. Just like loudspeakers, they transform electric energy into mechanical energy. A generator uses the reverse principle: it transforms mechanical energy into electric energy by displacing a conductor along a magnetic field.

Electric guitars employ magnetic pickups to convert the vibration of guitar strings into electric currents for amplification. This is in contrast to the concept behind the dynamic microphones and speakers because the vibrations are recognised straight by the magnet (no diaphragm is used).

Chemists employ nuclear magnetic resonance to identify manufactured compounds. Hospitals employ magnetic resonance imaging equipment to detect issues in a patient’s organs without surgery.

A compass has a magnetic pointer suspended to orient itself with a magnetic field. It will deflect according to the direction in which it is placed, relative to the Earth’s magnetic field.

Due to the magnets’ ability to counter the gravitational force at close range, magnets are often used in children’s toys.

Magnets can be used to pick up magnetic objects that are too small or out of reach. Several types of screwdrivers are magnetised for this use. Magnets are used in salvage and scrap operations to segregate magnetic metals from non-magnetic metals.
Magnets can also be used in fail-safe devices for some cable connections. The power cords of some electronic devices are magnetic to avoid accidental impairment to the port when tripped over. The power connection that uses Magsafe in the Apple MacBook is an example of it.

Magnetic levitation transport (maglev) is a type of transportation system that suspends, propels and guides vehicles through electromagnetic force. It efficiently reduces rolling resistance, enabling vehicles to move with tremendous speed (compared to conventional vehicles).
