Magnetic Effect of Electric Current

Magnetic 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…

Magnetic Material & Terrestrial Magnetism

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…

Electromagnetic Induction & Alternating Current

Electromagnetic Induction & Alternating Current Electromagnetic induction is the production of a potential difference (voltage) across a conductor when it is exposed to a varying magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831 though it may have been anticipated by the work of Francesco Zantedeschi in 1829. Around 1830…

Electromagnetic Wave

Electromagnetic Wave Light, microwaves, x-rays, and TV and radio transmissions are all kinds of electromagnetic waves. They are all the same kind of wavy disturbance that repeats itself over a distance called the wavelength. Electromagnetic waves are waves which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence…
