When an energy meter is connected to the circuit under test, alternating current flows through the current coil and the voltage coil. These alternating currents generate alternating magnetic fluxes in their respective iron cores. The alternating magnetic fluxes pass through the aluminum disk, inducing eddy currents in it. These eddy currents are then subjected to the force of the magnetic field, causing the aluminum disk to rotate (the driving torque).

The grow light is an artificial light source, usually an electric light source, designed to stimulate plant growth by emitting an electromagnetic spectrum suitable for photosynthesis. Plant grow lights are used in applications that do not have natural light or require supplementary light. For example: In winter, when daylight hours may not be enough to achieve the desired plant growth, grow lights are used to extend the time the plants receive light. If the plants do not get enough light, they will spindly grow. Grow light is similar to the spectrum of the sun, simulating outdoor conditions from the different colors, temperature and spectral output of the growing light, and changing the lumen output of the light. Depending on the type of plant being cultivated, the cultivation stage (germination/vegetative period or flowering/fruiting period) and the photo-period required by the plant, the specific range of the spectrum, the luminous efficiency and the color temperature are all desirable.
