The diagram shows a positive charge moving in a magnetic field. square B square In which direction is the magnetic force acting on the charge? into the screen out of the screen up down

To determine the direction of the magnetic force acting on a positive charge moving in a magnetic field, we can use the right-hand rule. According to this rule, if you point your thumb in the direction of the velocity of the positive charge (which is the direction of the conventional current) and your fingers in the direction of the magnetic field, your palm will point in the direction of the force on the positive charge.From the picture details, we have:- A positive charge moving from the 6th circle in the first row to the 12th circle in the second row, which indicates the direction of the velocity of the positive charge is to the right.- A blue arrow pointing from the 6th circle in the first row to the 12th circle in the second row, which also indicates the direction of the velocity.- A blue circle with a plus sign at the bottom right corner, which typically represents the direction of the magnetic field coming out of the screen/page.Step 1: Point your right thumb to the right (direction of the positive charge's velocity).Step 2: Point your right fingers out of the screen/page (direction of the magnetic field).Step 3: Your palm will face the direction of the magnetic force on the positive charge.Following these steps, your palm will face downwards.Answer: The magnetic force acting on the positive charge is directed downwards.
