Magnetic field and/or electrical current imaging systems utilizing magneto-optical indicator films (MOIF) based on magneto-optical material with in-plane single easy axis type of magnetic anisotropy provide improved magnetic field resolution and dynamic range with the use of specific illumination ...
Inducing Electric Current An electric field is induced only when a wire crosses the magnetic field lines. An electric current is induced because a magnetic force can cause electric charges to move. Electric Generator uses electromagnetic induction to change mechanical energy into electrical energy. the...
Extending the GMR Current Measurement Range with a Counteracting Magnetic Field Traditionally, current transformers are often used for current measurement in low voltage (LV) electrical networks. They have a large physical size and are... TY Poon,NCF Tse,RWH Lau - 《Sensors》 被引量: 11发表:...
The stresses are generated by the electromagnetic forces, which in turn are caused by the interplay between electric current and the self-induced magnetic field. The current flow is disturbed by the presence of the crack and so is the magnetic field, which is induced by the electric current. ...
An electric current source comprising point horizontal electric dipoles is proposed. An approximate description of the magnetic field from such a source is given. The environments considered are two-layer (2 semi-infinite media, typically the air and the sea) and three-layer (2 semi-infinite laye...
These observations and the simulation results indicate that the dayside polar cap electric field observed during strong northward IMF is produced by a direct electrical current coupling with the solar wind. 展开 DOI: 10.1029/JA093iA04p02749 被引量: 211 ...
When a conductor carries a current, it creates a magnetic field which interacts with any other magnetic field present to produce a force. This fact must be taken into consideration when designing large pieces of electrical equipment that handle very high current flows. For example, bus bars carry...
Researchers have discovered a magnetic equivalent to electricity: single magnetic charges that can behave and interact like electrical ones. 研究人员发现磁力等同于电力:单磁荷可以像电磁荷一样相互作用。 The loops of a magnetic field can be seen in the arrangement of iron filings ...
Example 2: Understanding Magnetic Field Strength Imagine two wires, Wire A and Wire B, running parallel to each other. Wire A carries a current of 10 A, and Wire B carries a current of 2 A. Both currents flow in the same direction. Without calculating specific values, compare the magneti...
