## What materials are used to make a transformer?

Apart from active materials like copper and cold rolled grain oriented silicon steel, a number of ferrous, nonferrous and insulating materials are employed for building up a transformer.

## How do you make a transformer?

The core of the transformer works to direct the path of the magnetic field between the primary and secondary coils to prevent wasted energy. Once the magnetic field reaches the secondary coil, it forces the electrons within it to move, creating an electric current via electromotive force (EMF).

## How do you design a transformer?

Designing a transformer using an example:

1. Sec.Volt-Amps(SVA) = Vs * Is = 60 * 4.44 =266.4VA.
2. Prim.Volt-Amps(PVA) = SVA / 0.9 = 296.00VA.
3. Prim.Voltage (Vp) = V2 / (n2/n1) = 60/0.5= 120V.
4. Prim.current (Ip) = PVA/Vp = 296.0/ 120 = 2.467A.
5. Core Area(CA) = 1.15 * sqrt(PVA) = 1.15 * sqrt(296) = 19.785 cm²

## Which core is best for transformer?

The core acts as a support to the winding of the transformer, but the core should not oppose or resist the magnetic flux. And the material of the core should have high permeability. Its hysteresis curve should have a small area and its coercivity should be very low. And soft iron is the best for that.

## What is the best material for the core of a transformer?

Soft iorn provides the best material for the core of a transformer as its permeability (μ) is very high. Its hysteresis curve is of small area and its coercivity is very low.
