📚 Topic Summary
The Right-Hand Rule is a crucial tool in physics for determining the direction of the magnetic force acting on a moving charge or a current-carrying wire within a magnetic field. It's all about aligning your fingers and thumb to represent different aspects of the situation and then seeing where your palm points! This lab activity is designed to help you visualize this rule in action.
Imagine a current-carrying wire placed within a magnetic field. To use the right-hand rule, point your fingers in the direction of the magnetic field, and your thumb in the direction of the current. Your palm will then face the direction of the magnetic force acting on the wire. Remember, the magnetic force is always perpendicular to both the velocity of the charge/current and the magnetic field.

Instructions: Match the term to its correct definition.
💡 Part B: Fill in the Blanks
The Right-Hand Rule helps us determine the direction of the __________ force. Point your __________ in the direction of the magnetic field (B) and your __________ in the direction of the current (I). Your __________ then points in the direction of the force (F). The magnitude of magnetic force on a single charge is given by the equation $F = qvB\sin(\theta)$, where $q$ is the charge, $v$ is the velocity, $B$ is the magnetic field strength, and $\theta$ is the angle between the velocity and the magnetic field.
🤔 Part C: Critical Thinking
Explain how the Right-Hand Rule would be different if we were dealing with negatively charged particles instead of positively charged particles. How would you adjust the rule to correctly determine the direction of the magnetic force in that scenario?
