UNDERSTANDING THE LANGUAGE OF PHYSICS
This optional preparatory course is for students
registered in Physics 115.3 to review math
concepts and techniques that are used in a
first-year physics course.
Earths Magnetic Field
The Earths geographic north pole
corresponds to a magnetic south pole.
The Earths geographic south pole
corresponds to a magnetic north pole.
Strictly speaking, a north pole should be a northseeking pole and a south pole a south-s
