Starting from the magnetic field vector, this paper analyzes the types of magnetic field commonly used in magnetic particle inspection, and puts forward the concept of magnetic field latitude in magnetic particle inspection for the first time. According to the magnetic field latitude, magnetic field ...
magnetic fieldfinite elementIt is well known about the difficulty that the learning of the magnetic fields represents for the students of engineering. On the other hand, the importance of the above mentioned magnetic fields in the electrical machines is huge. That is the reason why we have to ...
An electromagnet is a tightly wound helical coil of wire, usually with an iron core, which acts like a permanent magnet when current is flowing in the wire. The strength and polarity of the magnetic field created by the electromagnet are adjustable by changing the magnitude of the current ...
Some objects can be easily magnetized by even a weak magnetic field. However, when the magnetic field is removed, they lose their magnetism. Temporary magnets vary in composition: they can be any object that acts as a permanent magnet in the presence of a magnetic field. For example, soft ...
source fields(synonymously called lamellar, irrotational, or conservative fields) and vortex fields(synonymously called solenoidal, rotational, or nonconservative fields) Electric fieldsE (x,y,z)can be source or vortex fields, or combinations of both, while magnetic fieldsB(x,y,z) are always vorte...
Methods A digital Gaussmeter was used to measure the flux densities of static magnetic fields generated by two types of magnetic attachments, under four circumstances: open-field circuit; closed-field circuit; keeper and magnet slid laterally for a certain distance; and existence of air gap ...
Magnet is a material that produces a magnetic field. You must have seen the various types and shapes of magnets in various applications such as speakers, electric motors, actuators, and even in toys. Have you ever wondered how the magnets align themselve
Using magnetic force microscopy, the direction of the turned-up magnetization was detected and the switching field was measured. It was found that the value of the switching field of the turned-up magnetization at the antivortex core is smaller by about 1000 Oe than that at the circular ...
At present, all of them are interpreted as Magnetars — neutron stars with an anomalously strong magnetic field of ∼ 1014 − −1015 Gs at the ejection stage (E). The nature and mechanisms of energy release are far from clear. In the p-y diagram, they are shown as pink triangles ...
This relation falls into three branches corresponding to three types of the magnetic field structure: an open type with the field lines going in the interplanetary space, closed loop-like type and intermediate type including both configurations of field lines. The high-speed streams originate above ...
