Magnetic field matrak.

The magnetic field is unique at every point in space. 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. 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.

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. Meausure for how easily current. These packages solve maxwell s equations for the boundary value problem specified in a user defined situation. Weber wb kg m 2 a 1 s 2 m l 2 t 2 i 1.

Vector field magnetic flux. This is closely related to field strength but depends also on the material within the field. Magnetic field lines are continuous and unbroken forming closed loops. At such high frequencies it is very difficult for a sound wave to.

Measure of quantity of magnetism taking account of the strength and the extent of a magnetic field. Scalar magnetic flux density. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. Strength of a magnetic field in a material.

Magnetic field lines are defined to begin on the north pole of a magnet and terminate on the south pole. Do not confuse magnetic field strength with flux density b. A magnetic field is a vector field that describes the magnetic influence on moving electric charges electric currents and magnetized materials. Strength of a magnetic field in a material.

Measure for the received amount of radiation adjusted for the effect of different types of radiant on biological tissue. Hypersound sometimes called praetersound or microsound is sound waves of frequencies greater than 10 13 hertz. A magnetic field line can never cross another field line. Magnetic fields are a vector entity meaning that field magnitude and di rection are require d to completely describe them.

Measurements near appliances may be higher 9. Measure for the strength of the. Sievert sv m 2 s 2 l 2 t 2. The strict definition of h is.

Magnetic fields can also be calculat ed using several commercially avai lable simulation software packages. A synonym for the magnetic field.
