Magnetic Field Matrak

Vector field magnetic flux.

Magnetic field matrak. Strength of a magnetic field in a material. A magnetic field line can never cross another field line. A magnetic field is a vector field that describes the magnetic influence on moving electric charges electric currents and magnetized materials. Meausure for how easily current.

At such high frequencies it is very difficult for a sound wave to. Magnetic field lines are continuous and unbroken forming closed loops. A synonym for the magnetic field. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.

Measure for the strength of the. Measure of quantity of magnetism taking account of the strength and the extent of a magnetic field. Homes had magnetic fields below 0 6 mg and less than 1 percent of the homes exceeded 6 6 mg. The magnetic field is unique at every point in space.

Magnetic fields can also be calculat ed using several commercially avai lable simulation software packages. Measurements near appliances may be higher 9. Magnetic field strength cannot be measured in the same way because there is no magnetic monopole equivalent to a test charge. The effects of magnetic fields are commonly seen in permanent magnets which pull on magnetic materials such as iron and.

Sievert sv m 2 s 2 l 2 t 2. The time weighted magnetic field exposure of electrical occupations derived from job titles is estimated to be 1 2. This is based on measurements taken in the centre of rooms. Measure for the received amount of radiation adjusted for the effect of different types of radiant on biological tissue.

Do not confuse magnetic field strength with flux density b. On platforms etc the electric fields come from the overhead catenary wire in systems with overhead electrification and the magnetic field comes from the current loop formed by the supply the overhead catenary or the third rail and the return the running rails or a dedicated conductor. These packages solve maxwell s equations for the boundary value problem specified in a user defined situation. Earth s magnetic field also known as the geomagnetic field is the magnetic field that extends from the earth s interior out into space where it interacts with the solar wind a stream of charged particles emanating from the sun the magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in the earth s outer core.

Weber wb kg m 2 a 1 s 2 m l 2 t 2 i 1. Magnetic fields are a vector entity meaning that field magnitude and di rection are require d to completely describe them. Magnetic field lines are defined to begin on the north pole of a magnet and terminate on the south pole. Hypersound sometimes called praetersound or microsound is sound waves of frequencies greater than 10 13 hertz.

This is closely related to field strength but depends also on the material within the field. Strength of a magnetic field in a material.
