What This Document Is
This is a lab activity focused on exploring the principles of magnetic force, specifically the Lorentz force, within a General Physics (PHYS112) course at West Virginia University. It’s designed to be a hands-on learning experience, bridging theoretical concepts with practical application. The activity centers around investigating the forces exerted on current-carrying wires within magnetic fields, and the relationship between electric and magnetic fields. It builds upon foundational physics knowledge related to electromagnetism.
Why This Document Matters
This resource is ideal for students enrolled in a university-level General Physics course who are looking to solidify their understanding of magnetic forces. It’s particularly beneficial when preparing for laboratory sessions, as it outlines the core concepts that will be experimentally investigated. Students who struggle with visualizing magnetic fields or applying vector calculations will find this activity especially helpful. It’s best used *before* and *during* a lab session to maximize comprehension and experimental success.
Common Limitations or Challenges
This activity focuses on the *application* of magnetic force principles, and doesn’t serve as a comprehensive textbook replacement. It assumes a baseline understanding of vector mathematics, the right-hand rule, and fundamental electromagnetism concepts. It does not provide a complete theoretical derivation of the formulas used, nor does it cover every nuance of magnetic interactions. The activity is designed to be used in conjunction with lectures and assigned readings.
