The definition: "Electromagnetic induction is the production of voltage across a conductor situated in a changing magnetic field or a conductor moving through a stationary magnetic field." - wikipedia
Assuming the transformer is converting higher voltage electricity to lower voltage, the primary (high side) winding is energized by the power system. The highside winding being energized creates a magnetic field perpendicular to it. This magnetic field, in turn creates an electric field perpendicular to it, which causes current to flow in the secondary winding.
Number of turns in the primary vs. the secondary is equivalent to the multiple increase in current from primary to secondary.

How does a welding transformer work?
A welding transformer uses the alternating current supplied to the welding shop at a high voltage to produce the low voltage welding power
If I buy hair straighteners from the US will they work with UK plug sockets?
no. North America uses a 110 volt household current, UK. uses 220 volts. You would need a transformer to step down the current. The plug lay-out is also different.
How wireless chargers are working?
Inductive charging (also known as "wireless charging") uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device. Induction chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electrical current to charge the battery. The two induction coils in proximity combine to form an electrical transformer. Greater distances between sender and receiver coils can be achieved when the inductive charging system uses resonant inductive coupling.
Where can one find some common uses for induction heating?
There are many common uses for induction heating. Some include: use of the furnace, cooking, welding, etc. It needs a specific temperature to endure even heating with the source one is using.
What are the uses of transformer?
1.) It can rise down the level of level of Voltage in an AC Circuit. 2.) It can build or decline the estimation of capacitor, an inductor in an AC circuit. 3.) It can accordingly go about as an impedance exchanging gadget. 4.) It can be utilized to keep DC from going from one circuit to the next. 5.) It can seclude two circuits electrically.
What is the difference between discrete fourier transform and fast fourier transform?
discrete fourier transformer uses digital signals whereas the fast fourier transform uses both analog and digital.
Which is basic function of transformer?
It uses electromagnetic induction to transfer energy between separate circuits.
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
How do you test chopper transformer?
A chopper transformer is a kind of transformer used in an switching power supply.The primary input voltage of it is a Direct current (D.C) unlike any other ordinary step down transformer which uses an Alternating Current (A.C).Chopper transformer uses a switching transistor to produce a secondary voltage..
What are the uses of induction coils?
1. Transformer 2. DC/ AC Motors 3. Solenoid valves 4. Contactors/ Relays 5. Amplifiers
How does a welding transformer work?
A welding transformer uses the alternating current supplied to the welding shop at a high voltage to produce the low voltage welding power
What type of device is uses to increase or decrease the voltage of an electric current?
The device is called a "variac' and it is a type of transformer. It has a variable voltage ouput.
How does a transformer change voltage and current?
A welding transformer uses the alternating current supplied to the welding shop at a high voltage to produce the low voltage welding power
How does an electric cooker use electromagnetic induction?
An electric cooker uses electromagnetic induction by passing an alternating current through a coil of wire in the cooktop. This creates an oscillating magnetic field, which induces an electric current in the cookware placed on top of the cooktop. The resistance in the cookware generates heat, which cooks the food.
If I buy hair straighteners from the US will they work with UK plug sockets?
no. North America uses a 110 volt household current, UK. uses 220 volts. You would need a transformer to step down the current. The plug lay-out is also different.
What the uses of bus duct?
Busduct is useful for transforming current from switchgear end to transformer end.It has no voltage drop.But little bit expensive when compared to Cables.
