Instructional Ideas

• Provide additional examples for class do prior to assigning the homework for them to complete individually
• Find videos on the Biot-Savart Law on the Internet and share with the class

Classroom Considerations

• To do the demonstration, create a 2-turn coil of wire with a 1.5-foot diameter
• The seventh in a 14-part series

Pros

• The homework comes with an answer document
• The plan includes directions for a demonstration of the magnetic field around a current carrying wire

Cons

• The plan does not provide a clear instructional strategy
