Math Solution of Static Electricity Static electricity is an excess of electric charge trapped on the surface of an object. The charge remains until it is allowed to escape to an object with a weaker or opposite electrical charge, such as the ground, by means of an electric current or electrical discharge. Static electricity is … Read more
Last Updated: March 19, 2026 at 8:51 pmElectric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can be assumed that the resistance to current flow is a constant so that the current in the circuit is related to voltage and resistance by … Read more

Last Updated: March 19, 2026 at 8:51 pmMagnetic Effect of Electric Current When electric current flows through a wire wound around an iron bar, the bar behaves like a magnet. This magnet is called an electromagnet. An electromagnet is formed due to the magnetic effect of electric current. This magnetic effect of electric current was discovered by Hans Christian Oersted. Once, while … Read more

Magnetic Material & Terrestrial Magnetism Earth’s magnetic field (also known as the geomagnetic field) is the magnetic field that extends from the Earth’s inner core to where it meets the solar wind, a stream of energetic particles emanating from the Sun. Its magnitude at the Earth’s surface ranges from 25 to 65 µT. It is … Read more
