Math Solution of Magnetic Material & Terrestrial Magnetism

Math Solution of 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…

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…

Reflection of Light

Reflection of Light Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves. The law of reflection says that for specular reflection the angle at which…

Refraction of Light

Refraction of Light Refraction is the bending of a wave when it enters a medium where it's speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. The amount of bending depends on…

Optical Instrument

Optical Instrument When you use an optical device, it is something very simple like a magnifying glass, or more compound such as a telescope or a microscope, you're usually trying to make things more so that you can more easily see the fine details. One thing to remember in this regard is that if you want to…
