Short Answer

Explain what causes physical vibrations in transformers at twice the frequency of the AC power involved.

When AC passes through the coils of a transformer, magnetic materials can change their shape or size.

Step 1: Definition of frequency and AC power

The electromagnetic induction and mutual induction laws of Faraday are the foundation of how the transformer operates. On the transformer core, there are typically two coils: a primary coil and a secondary coil. Strips are used to link the core laminations. The mutual inductance of the two coils is very high.

The number of times a repeated event occurs per unit of time is known as frequency. It's also referred to as temporal frequency to distinguish it from spatial frequency, and ordinary frequency to distinguish it from angular frequency.

Energy storage components such as inductors and capacitors can cause periodic reversals of the direction of energy flow in alternating current circuits; the watt is the SI unit for this.

Step 2: Explanation

Vibrations in a transformer normally occur at twice the frequency of AC electricity. The AC that passes through the coils of a transformer has a magnetic impact on the core.

Magnetostriction in a magnetic core causes vibrations, which is the property of magnetic materials to change their shape or size during magnetization.
