The magnetic force does no work on a charge moving through a magneticfield.( )( )θcossFWB=, and since the angle between the s and FBvectors isalways 900the work done in displacing the charge is zero. Magnetic forces alone cannot alter the kinetic energy of a particle.FBright hand rule...

Magnets, or the magnetic fields created by moving electric charges, can attract or repel other magnets, and change the motion of other charged particles. A magnetic field exerts a force on particles known as the Lorentz force, according to Georgia State University's HyperPhysics website. The ...
(north) pole of the magnet to the S (south) pole of the magnet. In definition these lines never cross each other unless the magnetic field intensity is zero. It must be noted that magnetic lines of forces are a concept. They don’t exist in real life. It is a model which is ...
magnetic field noun : the portion of space near a magnetic body or a body carrying an electric current within which magnetic forces due to the body or current can be detected Medical Definition magnetic field noun : the portion of space near a magnetic body or a current-carrying body ...
Magnets and Magnetic Fields Objectives Identify examples of magnetic forces in everyday life. Describe the concept of a force field. Draw and interpret magnetic field diagrams. Describe basic properties of the Earth’s magnetic field, including its direction. ...
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. ...
