4 years ago. An electron can be deflected by magnetic as well as electric field. A magnetic field exerts a force on a moving charge, where the force is proportional not only to the field strength but also to the speed of the charged particle. The direction is perpendicular to the field and perpendicular to the direction of motion.

As with electric fields, the pictorial representation of magnetic field lines is very useful for visualizing the strength and direction of the magnetic field. As shown in Figure 20.9 , the direction of magnetic field lines is defined to be the direction in which the north pole of a compass needle points.
Magnetic fields arise from permanent magnets and electric charges in motion. Magnets can occur naturally (such as the Earth’s magnetic field), or they can be made by magnetizing ferromagnetic materials. Magnetic fields ultimately are the result of the motion of charges. A typical representation of this can be seen in the figure below.
Sep 12, 2022 · The magnetic force is directed where your thumb is pointing. If the charge was negative, reverse the direction found by these steps. Figure 11.3.1. 11.3. 1. : Magnetic fields exert forces on moving charges. The direction of the magnetic force on a moving charge is perpendicular to the plane formed by b →v. v ⃗.
Mar 9, 2022 · A magnetic field is an invisible force field generated by a magnet (like bar magnet and horseshoe magnet), moving electric charge (like current-carrying wire, toroid, and solenoid), spinning electrons, and changing electric field. The force due to a magnetic field is called magnetic force. This force can be detected in the presence of magnetic ...
May 16, 2024 · The magnetic field is sometimes referred to as magnetic induction or magnetic flux density; it is always symbolized by B. Magnetic fields are measured in units of tesla (T). (Another unit of measure commonly used for B is the gauss , though it is no longer considered a standard unit.
The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of motion have a magnetic attraction force between them. Similarly, objects with charge moving in opposite directions have a repulsive force ...
