MAGNETISM: REAL-LIFE APPLICATIONS NORASHIDA MOHD RAZALI,4SSCZ - Coggle…

- - - - :heartbeat:permanent magnet installed-->alarm activated-->respond to change in magnetic field-->break connection magnet and metal.
  - - - :heartbeat:Gauss developed simple instrument with permanent bar magnet suspend horizontally by gold wire.
  - - - :heartbeat:large tube in supine position-->activate powerful magnetic field-->atoms inside body spin-->machine beams radio signal at frequency same like body-->atoms burst energy absorbed from radio waves-->computer scans-->translate 3D images.
- - - - :sunflower:current flow back forth between diaphragm,+ve plate capacitor-->depend on electrical/electrostatic pull increase/decrease.
        
        :sunflower:produce ac,same frequency as sound waves,travel thru mixer and amplifier to speaker.
  - - - :sunflower:enter coil-->current induce magnetic field-->coil vibrate-->latter reproduce sound generate at source
  - - - :sunflower:bar move up down in field-->diaphragm vibrate-->produce sound magnified once released thru bell-shaped horn.
  - - - :sunflower:latter generate magnetic field-->draw towards iron attach to hammer-->hammer strike bell-->
        
        :sunflower:mechanical reaction push armature away from electromagnet-->spring force armature back against electromagnet-->cycle continue-->cause ringing of bell.
- - - - :icecream:disk drive:2 electric motors
        i) disk motor=rotate disk at high speed
        ii)head motor=move computer's read-write head across disk
        iii)stepper motor=ensure drive turn at precise rate of speed.
- - - - :neutral_face:can move many people,decrease environmental impact of automobile
