APPLICATION OF MAGNETISM IN REAL LIFE
Magnet for detection.
Magnetometer
Detecting the strength of magnetic field
Used by astronomer to detect the strength and direction of magnetic field surrounding the earth
Compass
Burglar alarm
Have contact switch that respond to the change of environment
Signal was send to make noise making device
MRI
Permit Dr. to make perfect diagnose without operate on patient body
By activate the powerful magnetic field that cause atom in the body to spin at certain frequency.
Magnet for projecting sounds
Microphone
Loudspeaker
Contain a circular permanent magnet that surround the electric coil
Current induces an alternating magnetic field cause the coil to vibrate
Car Horns
Uses magnetism to generate sound
Electric bells
Recording and Reading Data Using Magnets
Sound from microphone in form of alternating current
A small electromagnet that is magnetic field extend over the section of tape that been recorded
Loud sound produce strong magnetic field
Soft sound produce weak magnetic field
Maglev Train
