A transformer works because of two principles:
(a) magentic fields are created by the movement of charged particles - this includes electicity (electrons) moving through a regular cable.
(b) a conductor will induce a charge if it is moved through a magnetic field.
In a transformer the primary coil is powered which results in a magnetic field being produced, as per (a). Because the magnetic field generated by a single cable is very small a transformer uses a coil of several hundred loops to increase the magnetic field produced.
A transformer needs to be powered by AC (alternating current). In AC the direction of the current flow changes (e.g. mains power typically changes direction 50 to 60 times per second). As the AC power changes polarity so does the magnetic field and the North-South poles swap with the AC power.
This changing of magnetic poles is equivalent to moving the magnetic field around. Even though the secondary coil doesn't move, because the magnetic field is moving a current is induced in the secondary coil as per (b).
The number of loops in the primary coil compared to the number of coils in the secondary loop is used to control the strength of the magnetic field, the secondary coil induction effect and thus the output voltage. This is a simple ratio, so if the secondary coil has twice as many loops as the primary then the output voltage will be twice the input voltage.
There are two types of Transformers, "step up" where the voltage is increased and "step down" where the voltage is reduced.

Can gold transfer electricity?
Gold is an excellent conductor of electricity due to its high electrical conductivity. It is commonly used in electronics and electrical components where a reliable and efficient transfer of electricity is needed.
What are three things that transfer energy through electricity?
Three things that transfer energy through electricity are power lines, electrical cables, and batteries.
How would an air gap in the magnetic path affect the performance of the transformer?
An air gap in the magnetic path of a transformer increases the reluctance of the magnetic circuit, reducing the magnetic flux and efficiency of the transformer. This can lead to increased losses, lower power transfer efficiency, and potentially impact the regulation of the transformer. It is generally preferred to have a low-reluctance magnetic path for optimal transformer performance.
What Is the property of matter in which a substance can transfer heat or electricity.?
The property of matter that allows a substance to transfer heat or electricity is known as conductivity. Materials that are good conductors allow heat or electricity to flow easily through them, while materials that are poor conductors, or insulators, impede the flow of heat or electricity.
What is a complete path for transfer of electricity?
A complete path for the transfer of electricity involves a power source, conductive material (wires or cables) to carry the electricity, and a load (device or equipment) that uses the electricity. The electricity flows from the power source through the conductive material to the load, where it is converted into useful work. The path forms a closed loop circuit, allowing the electricity to continuously flow.
