A magnetic field is a physical field that is created by moving charges or electric currents and transmits interactions between them. It can be classified as static or dynamic, uniform or non-uniform, based on its characteristics and intensity levels. ...
A magnetic field is the area in which other objects can be affected by a magnet or moving charge. Observe the effect magnetic fields have on moving...
By the end of this section, you will be able to: Describe the effects of magnetic fields on moving charges. Use the right hand rule 1 to determine the velocity of a charge, the direction of the magnetic field, and the direction of the magnetic force on a moving char...
1) magnetic field of moving charge 运动电荷磁场 1. Transformation of electromagnetic field is derived from lorentz force formula andmagnetic field of moving charge. 从洛伦兹力公式和运动电荷磁场出发,导出了两惯性系间电磁场的变换关系。 2) Field of motional charge ...
byFaraday's Law of Induction, which is the basis for electromagnets, electric motors and generators. A charge moving in a straight line, as through a straight wire, generates a magnetic field that spirals around the wire. When that wire is formed into a loop, the field becomes a doughnut ...
A moving electric charge is surrounded by an electric field and a magnetic field. In its rest frame, an electric charge generates an electric field, but no magnetic field. Electric and magnetic fields are vector fields. Vector field,
By the end of this section, you will be able to: Describe the effects of a magnetic field on a moving charge. Calculate the radius of curvature of the path of a charge that is moving in a magnetic field. Magnetic force can cause a charged particle to move in ...
What causes Earth’s magnetic field? Magnetic fields are generated by electric charges in motion. In a bar magnet, the moving charges are electrons orbiting in atoms. In the Earth, they are electrons ferried around by circulating currents of molten iron. The details are not well understood....
magnet′ic field′ n. 1. a region of space near a magnet, electric current, or moving charged particle in which a magnetic force acts on any other magnet, electric current, or moving charged particle. 2. a vector quantity defined by the force exerted on a given object at each point...
