Discover the magnetic force on a charged moving particle and the importance of relative motion. Learn about the factors that affect its direction,...
Magnetic force is always perpendicular to velocity, so that it does no work on the charged particle. The particle’s kinetic energy and speed thus remain constant. The direction of motion is affected, but not the speed. This is typical of uniform circular motion. The...
1.The force that exists between two magnets, caused by the interaction of their magnetic fields. This force causes the magnets to attract or repel one another. 2.The force that exists between two moving, electrically charged particles, causing them to attract or repel one another. ...
A magnetic field and charged particle shield comprised of a plurality of permanently magnetized elements. In one embodiment, each element resembles a truncated pyramid with the pyramid base representing one pole and the top of the other pole and the elements are connected together to form a cube ...
magnetic force, attraction or repulsion that arises betweenelectrically chargedparticles because of their motion. It is thebasic forceresponsible for such effects as the action ofelectric motorsand the attraction ofmagnetsforiron.Electric forcesexist amongstationaryelectric charges; both electric and magneti...
The magnetic force is a force that acts on moving charged particles in a magnetic field, while the electric force is a force that acts on charged particles in an electric field. Additionally, the magnetic force is always perpendicular to the particle's motion, while the electric force can hav...

Magnetic fieldsforcemoving electrically charged particles in a circular or helical path. This force—exerted on electric currents...
A magnetic field exerts a force on particles known as the Lorentz force, according to Georgia State University's HyperPhysics website. The force acting on an electrically charged particle in a magnetic field depends on the magnitude of the charge, the velocity of the particle, and the strength...
However, a most interesting effect appears when a charged particle in a field is followed where the lines of force converge toward one another. By applying first approximation, the direction from which slow charged particles should enter the atmosphere; converging rays, forming auroral coronas, ...
1. If a charged particle moves in a straight line through some region of space, can you say that the magnetic field in that region is necessarily zero?Problems & Exercises 1. What is the direction of the magnetic force on a positive charge that moves as shown in each ...
