YOGYAKARTA - In everyday life, there are many tools that work with the principle of electromagnetic induction. However, most of us do not know what type of electronic equipment works with this principle.

Quoting the book High School Physics Class XII by Ali Yaz, electromagnetic induction is a process that can arise when a conductor is placed in a state of moving or changing magnetic field and is stationary. Then, the magnetic field produces a voltage along the conductor until an electric current appears.

This principle is the basis for many electronic devices that we often use every day. So, what are the tools that work with the principle of electromagnetic induction? Come on, find out the answer in the following review.

Devices that Work on the Principle of Electromagnetic Induction

Compiled from various sources, the following are some electronic devices that utilize the principle of electronic induction:

Loudspeaker

Electronic equipment that works on the principle of electromagnetic induction is a loudspeaker. The working mechanism is to convert an electrical current signal into a sound wave. The signal that passes through the coil in the form of a solenoid is located behind the speaker.

In a loudspeaker, the current flows in only one direction and the magnetic force will push the electromagnetic wave out of the loudspeaker. On the other hand, the opposite current will pull the speaker until it vibrates to produce a sound wave.

Electric Bell

The electric bell also works on the principle of electromagnetism. When the switch is pressed, an electric current flows through the coil, turning the iron core into a magnet. This magnet attracts the striker connected to the bell, causing the striker to hit the bell and produce a sound.

Electric Generator

An electric generator is a machine that can convert kinetic (mechanical) energy into electrical energy. Electric generators work by exploiting the electromagnetic principle, in which the relative motion between a conductor and a magnetic field produces an electric current.

Quoting the Lumen Learning page, an electric generator rotates a coil at a constant angular velocity within a magnetic field. This mechanism allows the generator to generate an electric force that varies sinusoidally over time.

Electrical generators are often used as a backup power source when the main power supply is interrupted.

Dinamo

Just like an electric generator, a dynamo converts mechanical energy into electricity. In order to generate power, the dynamo uses the principle of electromagnetic induction.

Dinamo has a coil of quats that is fed by a magnetic field and will produce electric motion power. The faster the rotation, the greater the CGL produced.

Not only that, the dynamo is also equipped with a magnetic coil that serves to strengthen the induced electric current produced.

Transformer

Other electronic equipment that works on the electromagnetic principle is a transformer. This tool serves to raise or lower current and voltage. The transformer is in the form of two coils with different numbers of turns.

Following the safety of the Physics of Boston University, the primary coil can generate a varying magnetic flux, so that the voltage on the secondary coil depends on its winding.
