Inventions

that use electromagnetic induction!

Number one: The Induction Cooktop

How does it work, you ask?

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

How does this work?

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

This handy product was invented by Michael Faraday in 1831. There are three main parts to an induction heater: the power head, the work unit, and the coil. Induction heating is a non contact method, instead magnetic fields become very useful. The induction heater is important in processes such as welding, and cooking. (See the induction cooktop!)

Number four: The Electric Generator

These convert kinetic energy into electrical energy. To make electric generators function, a wire coil is placed between two magnets and spins at a high speed. Because of this, an electric current is generated.

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

This vital piece of machinery was invented by Alva J. Fisher in 1908. How does this amazing appliance work you ask? It's simple! It contains the same induction motor that Tesla invented centuries prior, but with a twist. These washing machines use a three-phase version of the motor. In this type of motor, electromagnetic energy is transferred from a primary winding to a secondary winding separated by a gap of air. This is used in order to ensure a higher performance.

Number six: The Induction Rice Cooker

Have you ever finished a big bowl of rice and said "man that rice was unevenly cooked..."? I sure have! Well, your solution is here! The induction rice cooker works in almost the same way as the induction cooktop, but instead of the magnetic field only being at the bottom, the field is all around the cooker. This means your rice will be evenly cooked by the heat which surrounds it. Yum, tastier and more evenly cooked rice!



This was invented by Yoshitada Minami in 1988.

Number seven: The electric scooter

These sporty transportation devices are powered by a battery. The electricity from the battery passes through wires that wound in a loop around a magnetic field. The wires begin to spin, which makes the back wheel spin also. Now you know how your new scooter works!

Number eight: The Shaking Flashlight

This flashlight is said to be the eternity flashlight. This is because it is not battery powered. Instead, this tool uses electromagnetic induction. When a magnet inside hits the coil, a magnetic field is created. The idea of electromagnetic induction came from Michael Faraday.

Number nine: The Moka Pot

The Moka Pot is a stove top induction coffee maker. Similar to the induction rice cooker, this coffee maker uses magnetic fields to remain heated. Your coffee will never go cold again! These coffee makers will also make your coffee in record time! These were invented in 1933 by Alfonso Bialetti.

Number ten: The Induction Blanket Light

Have you ever worn a blanket, but still felt cold? While being cold inside of a blanket, have you ever wanted a light, but were to lazy to get up and turn one on? Well we have your solution. The Induction Blanket Light is a new invention. It is a blanket, that when shaken heats up, and lights up. How does it work? Coils of wire are inside, and when electricity passes through these wires, a magnetic field is created. This allows heat to be generated inside of the blanket. The blanket is made with glow in the dark fabric, so when you wear it you will always be warm and be able to see! The blanket must be plugged into an outlet while you wear it, or else it will not warm up. This was invented in 2013 by Maddie and Katrina.
