Description

Explore the interactions between a compass and bar magnet. Discover how you can use a battery and wire to make a magnet! Can you make it a stronger magnet? Can you make the magnetic field reverse?

نمونه ای از هدف های آموزشی

• Predict the direction of the magnet field for different locations around a bar magnet and electromagnet
• Compare and contrast bar magnets and electromagnets
• Identify the characteristics of electromagnets that are variable and what effects each variable has on the magnetic field's strength and direction
• Relate magnetic field strength to distance quantitatively and qualitatively
