Magnetic field testing is performed to test the magnetic resistance of electronic equipment in settings like high-voltage substations, facilities, and vehicles, ensuring they are resistant to transients. Magnetic transients can cause faults in video displays, hall effect sensors, and other sensitive devices.
Magnetic Field Indicators. Determining whether a magnetic field is of adequate strength and in the proper direction is critical when performing magnetic particle testing. As discussed previously, knowing the direction of the field is important because the field should be as close to perpendicular to the defect as possible and no more than 45 ...
The surrounding magnetic field is present only when there is an electrical current (i.e. the electricity is being transmitted or appliances are on), and its strength varies with power consumption (increased current = increased magnetic field). ELFM fields are measured in units of tesla (T) or gauss (G).

Equipment sometimes requires isolation from external magnetic fields. For static or slowly varying magnetic fields (below about 100 kHz) the Faraday shielding described above is ineffective. In these cases shields made of high magnetic permeability metal alloys can be used, such as sheets of permalloy and mu-metal [6] [7] or with ...
Since magnetic fields affect the line of electrons, there needs to be no external field around the scope tube. A mu-metal shield, like a can, is slipped over the sides of the tube. Containing the Field. Suppose you want to contain the magnetic field within an area and not allow it to spread out and affect other devices or your TV or other things.
The magnetic field will create a "sideways" change in electric potential across the material - which you can measure. Using this change in potential and the size of …

Magnetic Shielding Basics and Materials. 2 Jun, 2017. Magnetic fields can pose a problem for electronic equipment, and attempting to shield for magnetic fields is not as simple and straightforward as for electric fields. No material is actually able to block magnetic fields without itself being attracted to the magnetic force.

Effects of EMFs on equipment. There are several types of equipment that can be affected by fields. However, the fields required are usually rather higher than those commonly encountered in the environment. Credit cards, railway tickets etc have information encoded on a magnetic strip. This can be corrupted by magnetic fields above about 10,000 µT.
A magnetic field results from the flow of current through wires or electrical devices and increases in strength as the current increases. The strength of a magnetic field decreases rapidly with increasing distance from its source. Magnetic fields are measured in microteslas (μT, or millionths of a tesla).
SFM and Magnetic fields technology advantages: Higher field strength in the working zone for the mass and size of the magnet. Substitution of higher-temperature, lower-remanence materials. Increased design freedom, with less concern for handling stray field effects. Reduction of overall system weight for equipment using the SFM.

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents,: ch1 and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.: ch13 A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets.
presence of that field. Magnetic field: 1) A moving charge or current creates a magnetic field in the surrounding space (in addition to E). 2) The magnetic field exerts a force F m on any other moving charge or current present in that field. - The magnetic field is a vector field vector quantity associated with each point in space.
