Effect of The Earth’s magnetic field By X 9h Earth’s Magnetic Field Introduction Our Earth is a huge bar magnet tilted 11 degrees from the spin axis of the Earth‚ with geographic north pole being earth’s magnetic south pole and vice versa. Similar to how a magnet has a magnetic field surrounding it‚ our Earth also has its own magnetic field. The earth’s magnetic field is formed in the earth’s core due to a process known as the dynamo effect. According to dynamo effect

The magnetic separator is one of commonly used preparation equipments in magnetic separation factory. It has dry and wet two types. According to types of magnets‚ it can be divided into permanent magnet type and electromagnet type. It is also can be divided into strong magnet type‚ middle magnet type and weak magnet type according to the magnetic field strength. Different magnetic separators have different characteristics and performance. The common things have magnetite iron ore (belong to strong

Electron Gun - Effects of a Magnetic Field Purpose: The objective of this experiment is to study the motion of an electron in a magnetic field and to establish (show/verify) a relationship between the magnetic strength and the distance the electrons are deflected. Theory and Procedure: The electron gun is an instrument that consists of an electron source (which emits electrons and focus the stream into a beam)‚ a magnetic coil (which uses a voltage to create a magnetic field that deflects the beam

charge‚ i.e. charge to mass ratio ‚ of an electron using m Thomson’s bar magnet method. Basic methodology: Electrons in a CRT are deflected in the vertical direction by applying a potential between the vertical deflection plates of the CRT. A magnetic field perpendicular to the deflecting electric field is produced using a pair of bar magnets. The position of the magnets is adjusted so as to cancel the deflection of the electrons. The knowledge of the deflecting potential and the magnet field

Nuclear energy is needed according to the demands of the energy that creates electricity. Nuclear energy plays an important role in the air pollution because it reduces the carbon dioxide emitted to the air. According to the new research that was done by The Food and Agriculture Organization (FAO) of the United Nations (UN)‚ about the uses of nuclear technology‚ the radioisotopes and radiation used in food and agriculture to reduce these figures that was done 2014-2016 that shows 795 million people

The nuclear power stands on the border between humanity’s greatest hopes and its deepest fears for the future. But what happens inside a nuclear power plant to bring such marvel and misery into being? Imagine following a volt of electricity back through the wall socket‚ all the way through miles of power lines to the nuclear reactor that generated it. You’d encounter the generator that produces the spark and the turbine that turns it. Next‚ you’d find the jet of steam that turns the turbine and
