The force on a charged particle moving in a magnetic field is given by which law? (2021)
Step 1: Understand that a charged particle is a particle that has an electric charge, like an electron or proton.
Step 2: Know that a magnetic field is an area around a magnet where magnetic forces can be felt.
Step 3: Learn that when a charged particle moves through a magnetic field, it experiences a force.
Step 4: This force is calculated using a specific formula called the Lorentz Force Law.
Step 5: The formula is F = q(v × B), where F is the force, q is the charge of the particle, v is its velocity (speed and direction), and B is the magnetic field.
Step 6: The '×' symbol means that the velocity and magnetic field are being combined in a special way (cross product) to find the direction of the force.
