define 1 tesla? write down the expression of Lorentz force acting on a charge particle
Answers
Explanation:
Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric field E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by F = qE + qv × B.
ANSWER
Tesla is a unit of measurement for magnetic field strength. One tesla (symbol: T) is defined as the magnetic field strength that produces a force of one newton on a charge of one coulomb moving perpendicular to the field at a speed of one meter per second.
The Lorentz force is the force experienced by a charged particle that is moving through a magnetic field. The expression for the Lorentz force on a charge particle is given by:
- F = q(v x B)
where F is the force vector, q is the charge of the particle, v is the velocity vector of the particle, and B is the magnetic field vector. The symbol x represents the cross product operation.
EXPLANATION
This expression tells us that the Lorentz force on a charge particle is proportional to the charge of the particle, the strength of the magnetic field, and the velocity of the particle. The direction of the force is perpendicular to both the magnetic field and the velocity of the particle, and is determined by the right-hand rule.
Understanding the Lorentz force is important in many areas of physics, including the behavior of charged particles in particle accelerators, the interaction of particles with the Earth's magnetic field, and the operation of electric motors and generators.
