Earth's Magnetic Field

Try this

Using the Magnetometer tool, determine the strength of the Earth’s magnetic field in three dimensions. Using an understanding of vectors, determine the direction of the Earth’s magnetic field.

Challenge yourself

• Share magnetic field values with students across the globe, noting respective latitude and longitude values.
• Create a vector array of magnetic field values to observe the Earth’s whole gravitational field.
• Collect data over time, and observe changes in the Earth’s magnetic field due to solar activity.
