and so the charges spiral along the field lines. If field strength increases in the direction of motion, the field will exert a force to slow the charges, forming a kind of magnetic mirror, as shown below.
A planetary magnetic field refers to a vector field surrounding a planet that exerts a magnetic force on charged particles in its vicinity, with the intensity denoted by B. AI generated definition based on: Earth's Core, 2022 About this pageSet alert ...
The force acting on a charge 'q' moving with a velocity V in a magnetic field of induction B is given by View Solution A chargeqis moving in a magnetic field then the magnetic force does not depend upon View Solution Exams IIT JEE ...
The Lorentz Force Law exemplifies one of the ways these two forces interact with each other. Discover the Lorentz Force Law and learn how it's used to find the sum of both an electric field and a magnetic field's force on a charge. ...
1/00Force current1/8FORCE ON A CURRENT IN A MAGNETIC FIELDPURPOSE:To study the force exerted on an electric current by a magnetic field.BACKGROUND:When an electric charge moves with a velocity v in a magnetic fieldB, it experiences a magnetic force, called the Lorentz force,,(1)which ...
IV. Magnetic Force on Current-Carrying Wires: Similar to moving charges, wires carrying an electric current also experience a magnetic force when placed in a magnetic field. This phenomenon, known as the motor effect, plays a key role in the operation of electric motors and generators. The ma...
What is the force acting on a moving charge in a uniform magnetic field? Discuss the cases when the force is maximum and minimum and define the unit of magnet
Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron. Learn more abo
