Lesson 16 - Magnetic Fields III
... magnetic field was no longer aligned with the external magnetic field. If we release the current loop, the external magnetic field will do work on our current loop to realign the fields. Thus, magnetic potential energy was stored in turning the loop to the unaligned position and given up when the lo ...

Force on a coil
... A circular coil consists of 5 loops, each of diameter 1.0 m. The coil is placed in an external magnetic field of 0.5T (telsa). When the coil carries a current of 4.0 A, a torque of magnitude 3.93 Nm , acts on it . Find the angle between the normal to the plane of the coil and the direction of the ma ...

Study Notes Lesson 17 Magnetism
... In a motor, the current in the upper and lower sides of the loop is in opposite direction. The current is reversed during each half revolution by means of stationary contacts on the shaft. The parts of the wire that brush against these contacts are called brushes. The forces in the upper and lower r ...

![](https://en.wikipedia.org/wiki/Special:FilePath/Edward_Sabine_1860s.jpg?width=300)
General Sir Edward Sabine KCB FRS (14 October 1788 – 26 June 1883) was an Irish astronomer, geophysicist, ornithologist,explorer, soldier and the 30th President of the Royal Society.Two branches of Sabine's work are notable: Determination of the length of the seconds pendulum, a simple pendulum whose time period on the surface of the Earth is two seconds, that is, one second in each direction; and his research on the Earth's magnetic field. He led the effort to establish a system of magnetic observatories in various parts of British territory all over the globe, and much of his life was devoted to their direction, and to analyzing their observations.While most of his research bears on the subjects just mentioned, other research deals with the birds of Greenland (Sabine's gull is named for him), ocean temperatures, the Gulf Stream, barometric measurement of heights, arc of the meridian, glacial transport of rocks, the volcanoes of the Hawaiian Islands, and various points of meteorology.
