**What This Document Is**
This document is a student edition for an exploration of magnetic induction, designed for use with the “Magnetic Induction” Gizmo from ExploreLearning. It presents a guided inquiry activity where students investigate the relationship between electric current and the magnetic fields it creates. The document frames the exploration around using compasses to visualize and understand these magnetic fields.
**Why This Document Matters**
This resource is intended for Physics I students at the Massachusetts Institute of Technology (MIT) learning about electromagnetism. It serves as a preparatory activity, building intuition before diving into the more complex mathematical formulations of magnetic fields. It’s particularly valuable for students who benefit from hands-on, visual learning and for solidifying the concept of induced magnetic fields. This exploration is foundational for understanding motors, generators, and other electromagnetic devices.
**Common Limitations or Challenges**
This document provides a guided investigation within a simulated environment. It does *not* replace the need for a deeper theoretical understanding of electromagnetism, including Ampere’s Law and the Biot-Savart Law. It also doesn’t cover the mathematical calculations involved in determining magnetic field strength. The Gizmo provides a simplified model; real-world magnetic fields are often more complex.
**What This Document Provides**
This student edition includes:
* Prior knowledge questions to assess initial understanding of compasses and magnets.
* A guided warm-up activity introducing the Gizmo interface and the concept of magnetic fields.
* A structured activity (Activity A) focused on observing the relationship between current and induced magnetic fields, including predictions and tests.
* An introduction to the right-hand rule for determining the direction of magnetic fields.
* A second activity (Activity B) designed to explore the interaction between Earth’s magnetic field and induced magnetic fields using a magnetic field sensor.
* A prompt for a hands-on experiment to reinforce the concepts learned in the Gizmo.
This preview only includes the initial sections and activity setup. The full document contains the complete results of the Gizmo explorations, detailed observations, and further analysis questions.
