According to Lesson 2, a copper coil can attract to a permanent magnet like to one in the speaker if:

• It is touching a battery

• It is conducting electricity

• It is being moved against a magnet

• It has a certain number of coils

According to Lesson 4, forces in a magnetic field:

• Are the same at every point around the magnet

• Are always switching directions

• Follow a predictable path

• Can not travel without matter present

According to Lesson 4, a compass needle will always point North because:

• It is attracted to cold temperatures

• It is attracted to the sun

• It is attracted to Earth's magnetic field

• It is pulled that way by Earth's gravity

Why are we spending time figuring out how magnetic fields work? How does this help us understand the speaker system and how it works?

• We need to know how the parts of the system work together

• We need to know how the copper coil and the magnet affect each other without touching

• We needs to know what is forcing the cone of the speaker to move

• All of these are reasons we are investigating magnetic fields
