Questions & Step-by-Step Solutions

A charged particle moves in a magnetic field. What is the condition for it to experience maximum force?
  • Step 1: Understand that a charged particle is any 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 in a magnetic field, it experiences a force.
  • Step 4: Recognize that the strength of this force depends on the angle between the direction of the particle's movement and the direction of the magnetic field.
  • Step 5: Realize that the force is maximum when the particle moves at a 90-degree angle (perpendicular) to the magnetic field.
  • Step 6: Conclude that to achieve maximum force on the charged particle, it must be moving perpendicular to the magnetic field.
  • Magnetic Force on Charged Particles – The magnetic force experienced by a charged particle is given by the equation F = qvBsin(θ), where θ is the angle between the velocity vector and the magnetic field vector. The force is maximized when θ = 90 degrees, meaning the particle moves perpendicular to the magnetic field.
