A magnetic field is directed into the plane of the paper. If a positive charge moves to the right, what is the direction of the magnetic force acting on it? (2021)
Step 1: Identify the direction of the magnetic field. In this case, it is directed into the plane of the paper.
Step 2: Identify the direction of the positive charge's movement. Here, the charge is moving to the right.
Step 3: Use the right-hand rule to determine the direction of the magnetic force. Point your thumb in the direction of the charge's movement (to the right).
Step 4: Point your fingers in the direction of the magnetic field (into the paper).
Step 5: Your palm will face upwards, indicating the direction of the magnetic force acting on the positive charge.
Magnetic Force on a Charged Particle – The magnetic force acting on a charged particle moving in a magnetic field is determined by the right-hand rule, which relates the direction of the magnetic field, the velocity of the charge, and the resulting force.
