How a Magnetic Induction Water Heater Functions:
1. Fundamental of Electromagnetic Induction:
Electromagnetic induction involves creating an electric current in a conductor by varying the surrounding magnetic field. This process is guided by Faraday’s law of electromagnetic induction, where the movement of magnetic fields triggers an electric current in a conductive material.
2. Heating Process:
A magnetic induction water heater includes coils made of conductive materials like copper. When these coils have an alternating electric current passing through them, they generate a changing magnetic field around themselves.
3. Interaction with Water:
As water flows through or near these coils, the altering magnetic field induces electrical currents within the water because of its conductive properties. These induced currents lead to resistance in the water, producing heat due to the Joule heating mechanism.
4. Heat Transference:
The heat produced in this manner swiftly warms the water as it passes through the heater, effectively increasing its temperature. Since there is no direct contact between the heating element and the water, issues like scaling and mineral buildup are minimized, prolonging the heater’s durability.
