Motor to Generator Simulator - Electromagnetic Induction Motor to Generator Simulator Created by Ir. MD Nursyazwi This simulator demonstrates the **principle of a generator**, a machine that converts mechanical energy into electrical energy. It highlights how the same device can function as a motor (converting electricity to motion) and as a generator (converting motion to electricity). How to Use the Simulator **Choose Rotation Source:** Select a button below to power the generator with a **hand crank**, **wind**, or **hydro** force. **Adjust Parameters:** Use the sliders to change the magnetic field strength, coil area, and the number of turns in the coil. **Toggle Circuit:** The switch togg...

Piezoelectric Effect Simulator - Mechanical Stress & Voltage Generation Piezoelectric Effect Simulator Created by Ir. MD Nursyazwi This interactive simulator demonstrates the **piezoelectric effect**, the ability of certain materials to generate an electric charge in response to applied mechanical stress. Choose a material and apply pressure to it to see how a force can be converted into a voltage. History of Piezoelectricity The piezoelectric effect was discovered in **1880** by French physicists Jacques and Pierre Curie. They used a combination of crystal specimens including quartz, Rochelle salt, and tourmaline, and found that when these materials were compressed, they generated a measurable electric charge. Pierre Curie later went on to help develop the first piezoelectric quartz electrometer. The invers...
