Electromagnetic Induction Catalog

What is electromagnetic induction?

Electromagnetic induction is the process of generating current in a conductor by placing the conductor in a constantly changing magnetic field. This happens because the magnetic lines of force are applying a force on the free electrons in the conductor, causing them to move.

Who came up with electromagnetic induction?

The inventor of electromagnetic induction was Michael Faradary. He was a British chemist and physicist who contributed significantly to the study of electromagnetism and electrochemistry. He discovered electromagnetic induction in 1831.

Electromagnetic induction, generators, and motors

An electric motor is a device for transforming electrical energy into mechanical energy; an electric generator does the reverse, using mechanical energy to generate electricity. At the heart of both motors and generators is a wire coil in a magnetic field. In fact, the same device can be used as a motor or a generator.

Electromagnetic Induction products:

The Inventor is Joy Vergese from Calicut, India.

Apparatus for self-generating a driving force.

Price: $465.00
This invention relates to an apparatus for self-generating a driving force, which employs an electromotive force generated on a coil by an electromagnetic induction, in combination with a mechanical driving device to drive a rotating shaft of the device, such that the rotating shaft can rotate continuously without any external power after an initial activation. The apparatus comprises a mechanical driving device, at least two coils, wherein the mechanical driving device includes arms in attachment with magnetic bodies, thereby an opposite electromotive force can be generated based on an electromagnetic induction to apply a force on the magnetic bodies for a rotation of the shaft.
The inventors are Yeh Show-Jong and Tu Yu Ta. Jheh Show-Jong has around 36 patents. Tu Yu Ta has around 84 patents.

Electric Generator

Price: $900.00

An electric generator is a device that converts mechanical energy to electrical energy. The reverse conversion of electrical energy into mechanical energy is done by a motor. A generator forces electrons in the windings to flow through the external electrical circuit. It is somewhat similar to a water pump, which creates a flow of water but doesn’t create the water inside. The source of mechanical energy may be a reciprocating or turbine steam engine, water falling through a turbine or waterwheel, an internal combustion engine, a wind turbine, a hand crank, compressed air or any other source of mechanical energy.

The inventor was Alioiso Galvani. He was Italian and he was born in the year of 1937. He is mostly known for bio electricity and animal electricity. Today, the study of galvanic effects in biology is called electrophysiology.


Price: $505.00

The transformer is a device used to increase or decrease AC voltage. The change of voltages causes relatively little loss of energy, which makes it good to use. Many of the devices we use at have transformers as a part of their cords .

Self-inductance produces an EMF when current changes in a single coil. A transformer has two coils that are electrically insulated from each other although wound around the same iron core. One of the coils is called the primary coil while the other one is called secondary coil. When the primary coil is connected to a source of AC voltage, the changing current creates a changing magnetic field that is carried through the core to the secondary coil. In the secondary coil, the changing field induces a varying EMF. This effect is called mutual inductance.

The inventor of the transformer is Otto Blathy. Otto Blathy was a Hungarian electrical engineer. He helped in the creation of an electric transformer, stabilizer, wattmeters, etc.

current clamp

Price: $110.00

A current clamp is an electrical device that has two jaws that when opened, allow clamping around an electrical conductor. This allows properties of the electric current in the conductor to be measured without having to make physical contact with the conductor. That is why they are so useful to humans today, they contribute with our health.

The inventor of the current clamp was Daniel Arnoux. He has patented 55 artifacts in his life.

Magnetic flow meter

Price: $1491.00
A magnetic flow meter is a volumetric flow meter which does not have any moving parts and is ideal for wastewater applications or any dirty liquid which is conductive or water based.
The operation of a magnetic flowmeter is based upon Faraday's Law, which says that the voltage induced across any conductor as it moves at right angles through a magnetic field is proportional to the velocity of that conductor.
The inventor of the magnetic flow meter is Reinhard Woltmart, he was born in Germany and he was a hydraulic engineer.

graphics tablet

Price: $49.00

A graphics tablet is a computer input device that enables a user to draw images and graphics, similar to the way a person draws images with a pencil and paper, but the images instead of being displayed on the tablet are displayed on the monitor of a computer. Electromagnetic induction makes life better by allowing us to use a pen and a tablet to draw instead of a mouse.

The inventor of the graphics tablet is Elisha Gray. He was an American inventor and he was brought up in a farm. He fought with Graham Bell to be the legal inventor of the telephone.

Hall effect meter

Price: $916.00

The hall effect meter is an electronic device that provides a digital readout of the magnetic field strength in either gauss or tesla units. In a magnetic field, a force is exerted on the moving electrons which tends to push them to one side of the conductor. A buildup of charge at the sides of the conductors will balance this magnetic influence, producing a measurable voltage between the two sides of the conductor.
The hall effect meter is named after its inventor, Edwin H. Hall. He was an American physicist who spent the majority of his career conducting thermoelectric research at Harvard University. Additionally, he wrote many textbooks and laboratory manuals

Induction sealing

Price: $107.00
Induction sealing is a process where aluminium foil seal across a bottle's neck. Induction sealers transmit an electromagnetic field which create eddy currents in a metallic element, such as an aluminium foil induction inner seal, placed in the magnetic field. This current heats the aluminium foil seal and its plastic coating bonds to the container neck.
The inventor of the induction sealing is Jack Palmer. He has patented over 7 inventions.

Wireless A/C

Price: $300.00
This wireless AC works the same way as a generator; it does not need wires. Inside there is a small coil that can be rotated by hand for 5 seconds to turn the AC on. Then, this coil will begin rotating faster and faster thanks to a moving magnet that will be inside.
The wireless AC was invented by Jamie Ruiz and Emily Garza in 2018.
