Questions & Step-by-Step Solutions
A current-carrying wire is placed in a magnetic field. What is the direction of the force acting on the wire?
Step 1: Identify the direction of the current in the wire. This is the direction in which positive charges would flow.
Step 2: Identify the direction of the magnetic field. This is usually indicated by arrows or lines showing the field's direction.
Step 3: Use your right hand to apply the right-hand rule. Point your thumb in the direction of the current (the flow of positive charges).
Step 4: Point your fingers in the direction of the magnetic field lines.
Step 5: Your palm will face in the direction of the force acting on the wire. This force is perpendicular to both the current and the magnetic field.
Magnetic Force on a Current-Carrying Wire – The force experienced by a wire carrying an electric current when placed in a magnetic field, determined by the right-hand rule.
