Then they cannot be treated independently of each other, because the changing electric field produces a changing magnetic field and the newly produced changing magnetic field produces a changing electric field, which is an electromagnetic wave. Therefore, considering the relationship given by Maxwell's...
A phenomenon where a changing magnetic field can produce an electric current in a conductor. What is this called? A. Gravity induction B. Magnetic induction C. Electric induction D. Friction induction 相关知识点: 试题来源: 解析 B。解析:磁生电的现象被称为电磁感应,也就是变化的磁场能在导体中...
其次, when/where it happens:在这里,我们需要指出”where it happens”。 Magnetic field 是在iron core里变化,the induced p.d. 存在于 secondary coil。最好,我们将这些点串起来:alternating p.d. applied in the primary coil causes the changing magnetic field, which induces alternating p.d. in the ...
Magnetic flux is a measurement of the total magnetic field that passes through a given area. Magnetic flux is a way of describing the amount of magnetic force on something of a given area. Answer and Explanation:1 A changing magnetic field induces an electric field. If a loop of wire is ...
Classical Electromagnetic Interaction of a Point Charge and a Magnetic Moment: Considerations Related to the Aharonov-Bohm Phase Shift in the magnetic moment; however, the electric field back at the point charge due to the Faraday-induced changing magnetic moment is of order 1/c 4 ... TH Boyer...
The magnetic field changing over the southern African continent: a unique behaviour High-quality magnetic observations have been obtained in recent years from a number of satellite missions. The satellite-based magnetic data, combined with... M Mandea,M Korte,D Mozzoni,... - 《South Af.j....
Now, Noboru Ikeya and Jonathan Woodward at the University of Tokyo have shown that a magnetic field causes chemical changes that can affect cellular behaviour. They achieved this with the aid of a cellular chemical that fluoresces depending on the external magnetic field. When they waved a magne...
A magnetic field, which causes a magnetic force and alters the flow, is one of the most important parameters in this context. This is crucial for requests in districts like the development of crystal in fluids, photoelectric bundle, and atomic reactor abating. Consequently, it is fundamental ...
Furthermore we find that although the system is nominally in a stale of equilibrium, the presence of the magnetic field causes the flow of oppositely directed currents which are tangential to the electrodes and occur at different points in the inter-electrode space, only the sum of such ...
The phase, frequency and amplitude of these two tones can be jumped for arbitrary rotations on the Bloch sphere, for selecting different momentum-changing transitions, velocimetry and so on. The third RF tone starts near 100 MHz but is continuously ramped in frequency at a rate of 2kg∥ ...
