Physics - Lesson on Magnetic Fields.

Summary
Students visualize the magnetic field of a strong permanent magnet using a compass. The lesson begins with an analogy to the effect of the Earth's magnetic field on a compass. Students see the connection that the compass simply responds to the Earth's magnetic field since it is the closest, strongest field, and thus the compass responds to the field of the permanent magnets, allowing them the ability to map the field of that magnet in the activity. This information will be important in designing a solution to the grand challenge in activity 4 of the unit.

Engineering Connection
This lesson covers magnetic fields and also serves as an introduction to vector fields, which are a common theme through most electrical engineering disciplines. As discussed in the lesson closure, understanding the Earth's magnetic field is important in designing ways of protecting astronauts in space. Students will act as engineers when they use their understanding of magnets to design devices to solve the problem presented in the grand challenge later in the unit.

Learning Objectives
After this lesson, students should be able to:
Explain the significance of the directions of magnetic field lines.
Draw the shape of magnetic field lines around a permanent magnet.

Okay thank you for the magnetic field
What about electromagnetic field
