Magnetic Field Matrak

These packages solve maxwell s equations for the boundary value problem specified in a user defined situation.

Magnetic field matrak. The strict definition of h is. Measure of quantity of magnetism taking account of the strength and the extent of a magnetic field. Measure for the received amount of radiation adjusted for the effect of different types of radiant on biological tissue. Strength of a magnetic field in a material.

A synonym for the magnetic field. Hypersound sometimes called praetersound or microsound is sound waves of frequencies greater than 10 13 hertz. The magnetic field is unique at every point in space. 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. Do not confuse magnetic field strength with flux density b. Meausure for how easily current. Strength of a magnetic field in a material.

Homes had magnetic fields below 0 6 mg and less than 1 percent of the homes exceeded 6 6 mg. The effects of magnetic fields are commonly seen in permanent magnets which pull on magnetic materials such as iron and. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. A magnetic field line can never cross another field line.

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. Measure for the strength of the. Vector field magnetic flux. A magnetic field is a vector field that describes the magnetic influence on moving electric charges electric currents and magnetized materials.

At such high frequencies it is very difficult for a sound wave to. Scalar magnetic flux density. 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 fields can also be calculat ed using several commercially avai lable simulation software packages. This is based on measurements taken in the centre of rooms. The time weighted magnetic field exposure of electrical occupations derived from job titles is estimated to be 1 2. 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.

Ultrasonics vibrations of frequencies greater than the upper limit of the audible range for humans that is greater than about 20 kilohertz the term sonic is applied to ultrasound waves of very high amplitudes. Magnetic field lines are defined to begin on the north pole of a magnet and terminate on the south pole.
