that use electromagnetic induction!
Number one: The Induction Cooktop
Well, coils that are just below the cooktops surface have an alternating current. This produces a magnetic field. Then, when cookware is placed in the magnetic field, it is like the second conductor, and a current is induced on it. That current becomes heat inside the pot or pan, and cooking food is made possible!
The induction cooker was first introduced at the 1933 world's fair.
Number two: The Rechargeable Toothbrush
When two parts of a transformer, that is inside the brush, are brought together a small magnetic field is created. Then a resulting electric charge will give the battery power. But don't worry, these electrical parts will not be damaged by water!
The Swiss inventor Dr. Philippe Guy Woog is credited with this invention.
Number Three: The Induction Heater
Number four: The Electric Generator
Although Alosio Galvani was the first inventor, Michael Faraday improved on the original design and made it what it is today.
Number five: The Induction Washing Machine
Number six: The Induction Rice Cooker
This was invented by Yoshitada Minami in 1988.
