Questions & Step-by-Step Solutions

What is the right-hand rule used for in magnetism?
  • Step 1: Understand that the right-hand rule is a way to visualize the relationship between current, magnetic fields, and force.
  • Step 2: Hold your right hand in a specific way: point your thumb in the direction of the current (the flow of electric charge).
  • Step 3: Extend your fingers in the direction of the magnetic field lines (from north to south).
  • Step 4: Your palm will then face in the direction of the force experienced by a positive charge in the magnetic field.
