Electric and Magnetic Fields - Assignment ExampleThe constitution tells that the force of magnetism acts in a region around a moving electric belt or a magnet this region is defined as a magnetized playing field. It is shown in Fig. 1. The magnetised field can be conceptualized in hurt of charismatic field lines. The density of field lines determines the field strength, Magnetic flux is defined as the total number of lines of the magnetic field that pass through and through an area. Magnetic flux is measured in terms of Tesla quantify squared (T m2) another name for which is weber (Wb). A magnetic fields intensity can be expressed in terms of the magnetic field strength. A distinction can be technically made between magnetic flux density B and magnetic field strength H. Magnetic flux density is besides called teslas (T) and is measured in Newton-meters per ampere (Nm/A) whereas magnetic field strength is measured in terms of amperes per meter (A/m). The density of magnetic flux reduces as the distance is increased from a straight line that connects magnetic poles pair around which there is a stable magnetic field. There is direct proportionality between the magnetic flux density and the current in amperes at a stead in a current carrying wires vicinity. A piece of iron or some other ferromagnetic object when brought inside a magnetic field experiences a force known as the magnetic force which is directly proportional to the magnetic field strengths gradient with respect to the location of the object. In telecommunications, a measuring device known as field strength meter is utilise to measure the electric field that a transmitter causes. Magnetometers are the devices used to measure the strength of a magnetic field. Some important magnetometers classes comprise use of a rotating coil, NMR magnetometers, fluxgate magnetometers, SQUID magnetometers, and Hall return magnetometers.
