Keywords: Linear induction flashlight.jpg shaking flashlight powered by muscle power so it doesn't require batteries It contains a linear electric generator which generates electric current when the flashlight is shaken lengthwise The current charges a batterylike ultracapacitor which provides energy to power the LED lamp bulb The linear generator consists of a coil of wire visible in center of tube and a cylindrical neodymium magnet to right of coil which slides in a tube through the center of the coil when the flashlight is shaken Its magnetic field induces current in the coil by electromagnetic induction when it slides through 10 seconds of shaking provides about 2 to 3 minutes of light 2012-01-28 own Chetvorno cc-zero Uploaded with UploadWizard Linear alternators Dynamo torches Human-powered electronics ImageNote 1 1232 275 293 390 2298 924 2 Coil of wire generates current when magnet slides through it ImageNoteEnd 1 ImageNote 2 1594 382 290 158 2298 924 2 Neodymium magnet in plastic tube slides back and forth through coil when flashlight is shaken ImageNoteEnd 2 ImageNote 3 480 224 290 459 2298 924 2 Switch and ultracapacitor which stores current from coil are in this section ImageNoteEnd 3
