Electromagnetic Induction
Inventions
What is Electromagnetic Induction?
Who discovered it?
38'' Induction Cooktop $2,500
Uses induction heating to directly heat a cooking vessel, as opposed to using heat transfer from electrical coils or burning gas as with a traditional cooking stove.
Electric Guitar $300
Sound from an electric guitar is produced by electromagnetic pick-ups that sense vibrations in the strings electronically and route the electronic signal to an amp and speaker.
Washing Machine $735
Contains electric motor that takes advantage of electromagnetic induction.
Transformer $150
A static electrical device that transfers energy by inductive coupling between its winding circuits.
Graphic Tablet $80
A computer input device that enables a user to hand-draw images and graphics, similar to the way a person draws images with a pencil and paper.
STAR Electric Generator $133
uses electromagnetic induction to convert mechanical rotation into direct current through the use of a commutator.
Electric & Rechargable Toothbrush $65
Never have to buy batteries for your toothbrush again, it is always powered up and ready to go.
Rowland Ring *FREE*
An experimental arrangement for the measurement of the hysteresis curve of a sample of magnetic material. It was developed by Henry Augustus Rowland. Has been here forever come by & it's all yours.
Seymour Duncan Pickups $25 Each
Transducer that captures mechanical vibrations, usually from suitably equipped stringed instruments such as the electric guitar, or electric violin, and converts them to an electrical signal that is amplified, recorded, or broadcast.
ELECTRIC VEHICLE $25,000
