Questions & Step-by-Step Solutions

A charged particle moves in a magnetic field. What is the path of the particle if it enters the field perpendicularly? (2023)
  • Step 1: Understand that a charged particle is a particle with an electric charge, like an electron or proton.
  • Step 2: Recognize that a magnetic field is an area around a magnet where magnetic forces can be felt.
  • Step 3: Know that when a charged particle enters a magnetic field, it experiences a force due to the magnetic field.
  • Step 4: If the particle enters the magnetic field perpendicularly (at a right angle), the magnetic force acts on it.
  • Step 5: This magnetic force acts as a centripetal force, which means it pulls the particle towards the center of a circular path.
  • Step 6: As a result, the charged particle will move in a circular path while it is in the magnetic field.
  • Magnetic Force – A charged particle experiences a magnetic force when moving through a magnetic field, which is perpendicular to its velocity.
  • Centripetal Force – The magnetic force acts as a centripetal force, causing the particle to follow a circular trajectory.
  • Right-Hand Rule – The direction of the magnetic force can be determined using the right-hand rule, which helps visualize the motion of the particle.
