A magnet produces a vector field, the magnetic field, at all points in the space around it. It can be defined by measuring the force the field exerts on a moving charged particle, such as an electron. The force (F) is equal to the charge (q) times the speed of the particle times ...

What is H in magnetic fields? What is a magnetic field sensor? What is a geomagnetic reversal? What is magnetic north? What is magnetic immobility? What is magnetic resonance? What is a magnetic monopole? What is magnetic declination?
What is a magnetic field, how is it defined and what does it tell you? What is magnetism? Define Magnetic Field. What are magnetic waves? What is a magnetic dipole? What does magnetic energy mean? What are the sources of electric field and magnetic field?
Magnetic field strength, also called magnetic field intensity, is sometimes measured inoersted(Oe) rather than A/m. The oersted is part of the Gaussian system of units, which is based on the centimeter-gram-second (CGS) system. One Oe is equal to 79.577472 A/m, and one A/m is equal ...
What effect does a magnetic field have on a beam of radiation containing a mixture of alpha particles，beta particles，and gamma rays？这题的意思是：磁场对含有α粒子，β粒子，还有γ射线混合物的辐射光束有什么影响？Alpha particles are attracted to the negatively charged pole .Beta ...
Anyway, I still believe in principle we can marshal magnetic field strength energy to build such a device. The problem right now is that of magnetic field strength vs distance. That is, the further away you get from a field, the less force it exerts. ...
a large region of space immediately inside of the orbit of the Earth. The space within a magnetic cloud is a region of magnetic flux where a large scale rotation of the magnetic field of the Earth takes place. The field rotation of a magnetic cloud has been projected as of 1981 to be ...
What is it that directly gives off aurora light? A. The Earth’s magnetic field. B. The solar wind’s magnetic field. C. The Earth’s ionized particles. D. The solar wind’s charged particles. 相关知识点: 试题来源: 解析 C
The standard model for these systems is a white dwarf that accretes matter from a red dwarf companion that is overflowing its Roche lobe. The in falling matter can form an accretion disk before it is coupled to the magnetic field close to the white dwarf. In general they do not exhibit ...
