lab 6 .

Purpose

In this lab, you will explore how changing magnetic fields produce electric current. You will gather evidence, create representations (graphs & diagrams), and explain how induction works.

Learning Goals

• Identify conditions that produce electromagnetic induction
• Predict how induced current changes when conditions are varied
• Interpret and create graphs and diagrams of induced current
• Compare tools used to detect current

Key Idea

= N / t

Simulation

---

Part 1: Discovering Induction

• List at least 4 ways to produce induction
• Describe what evidence shows current is present

Required Sketch #1:

• Draw one setup that produces induction
• Label: magnet, coil, motion, and direction of current (if visible)

---

Part 2: What Affects Induction?

Using the Pickup Coil tab, investigate variables such as:

• Speed of motion
• Direction of motion
• Strength of magnet
• Number of loops

Required Graph #1:

• Create a graph of induced current vs. time
• Include at least one case where direction changes
• Label axes clearly

Explain: What causes the graph to change shape?

---

Part 3: Direction of Current (Lenzs Law Thinking)

Observe how the direction of current changes when:

• The magnet moves toward the coil
• The magnet moves away from the coil

Required Sketch #2:

• Draw BOTH situations (toward vs away)
• Show direction of motion
• Show direction of induced current

Explain: Why does the current reverse?

---

Part 4: Measuring Current

• Compare the light bulb and voltmeter

Required Comparison:

• What does each tool show clearly?
• What does each miss?

---

Part 5: Design an Experiment

Design an experiment to test how the size and direction of current change.

Include:

• Variable you change
• What you measure
• Prediction

Required Data Table:

• At least 5 trials
• Clear pattern or trend

Required Graph #2:

• Graph your experimental results
• Must show a relationship (not just points)

---

Part 6: Summary

Write a short explanation that answers:

• What causes induction?
• What affects how strong it is?
• What determines direction?

---

What to Submit (Canvas)

Submit ONE organized document (PDF preferred) that includes:

• Answers to all questions
• Sketch #1 (induction setup)
• Sketch #2 (direction comparison)
• Graph #1 (current vs time)
• Data table from experiment
• Graph #2 (experimental results)
• Final summary

Formatting Expectations:

• Format must maintain all of the following section introduction, methods, results, and conclusion
