HEADING Induction Stove
As it is said in the law of matter “Energy is neither created nor destroyed, it is transformed from one form to another”, energy is needed for the survival of everything in the world. Energy is gathered from a host of different sources and through different means. Plants gather their energy from harvesting natural energy from the sun. Animals on the other hand do not create their own energy they gather their energy from the consumption of food. Based off of this principle, the importance of the following device is highlighted. The induction stove is a relatively new technology as compared to the more popularly known methods of cooking eg. The gas stoves and the electric stoves. This induction stove is basically operates on the principle of induction based on faradays experiments with magnetic fields.
The induction heater is a counter top stove that uses an electromagnetic coil with a current flowing through it, which generates a magnetic field around it. When this field is cut by a conductor i.e. metal pot base heat is generated in the conductor/pot and then the heat is transferred to the food during cooking. This process is very energy efficient as it heats the pot directly and no heat transfer needs to take place as in between a flame and a pot. So it’s a fully efficient process and because of this heating time is greatly reduced

Faraday concluded that an electric current can be produced by a changing magnetic field.
• A current cannot be produced by a steady magnetic field.

A: Aluminum Plates
The non-magnetic properties of Aluminum makes it a suitable material to place beneath the burners to protect complex electronics from electromagnetic fields and from the high temperatures produced during cooking.

B: Ferrites
Ferrites underneath the copper coils resist the magnetic field, focusing the field on the pot directly above.

C: Insulated Gate Bipolar Transistor
The Transistor cuts up the electric current’s wavelengths, rapidly switching the power on and off. The process impulses the pan’s electron fields in and out of alignment, producing heat through intermolecular rubbing.

D: Central Processing Unit
The CPU propels current to the respective inductor coil, which yields a magnetic field. Sensors connected to the CPU perceives and upholds the temperature of the pan.

E: Wiring to CPU ; Burners
Copper conductors, bundled to uniformly dispenses the load, conveys the current from the breaker panel to the CPU
F: Cookware Sensors
Sensors in each coil/inductor detect the temperature of the cookware on top. This safety feature ensures that the current deactivates if the cooktop overheats.

G: Inductors (Burners)
These copper coils’ magnetic fields induce heat-producing currents in the cookware.

H: Control Panel
The heat settings are displayed digitally on a numerical scale


The heat generated in the induction heater is created from the constant shifting of the magnetic fields created from the coils. the tightly wound copper coils are located under the heating pads. When AC current is fed to the coils, it induces a magnetic field that is constantly shifting because of the Alternating current created by it.
Inside each cooking zone, there’s a tightly wound coil of metal. When you turn on the power, an alternating current flows through the coil and produces an invisible, high-frequency, alternating magnetic field all around it. Unless there’s a pan on the cooking zone, no heat is produced: the cooking zone remains cold. You might be wondering why we need a high frequency. Although your home power supply alternates at about 50–60Hz (50–60 times per second), an induction cooktop boosts this by about 500–1000 times (typically to 20–40kHz). Since that’s well above the range most of us can hear, it stops any annoying, audible buzzing. No less importantly, it prevents magnetic forces from shifting the pan around on the cooktop.

HEADING : Electromagnetic gun
An electromagnetic gun or rail gun as it is more commonly know is a military weapon that uses electromagnetic force to operate. It consists of a sliding amateur that is located between two conductive rails. It is used to shoot projectiles at very high velocity. They were designed to decrease the use of propellants for weapons artillery eg. Rocket propulsion grenades. A design of the gun is hsown below:
