Questions & Step-by-Step Solutions
If a magnetic field is directed into the page and a positive charge moves to the right, what is the direction of the magnetic force acting on the charge?
Step 1: Identify the direction of the velocity of the positive charge. In this case, it is moving to the right.
Step 2: Identify the direction of the magnetic field. Here, it is directed into the page.
Step 3: Use the right-hand rule: Point your right thumb in the direction of the velocity (to the right).
Step 4: Now, point your fingers in the direction of the magnetic field (into the page).
Step 5: Look at your palm. It will face out of the page. This indicates the direction of the magnetic force acting on the positive charge.
Magnetic Force on a Charge – 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 velocity, magnetic field, and force.
Right-Hand Rule – A mnemonic used to determine the direction of the magnetic force on a positive charge moving in a magnetic field.
