36 which of the following is true about the magnetic field diagram below

AP Physics B Exam 13 Magnetic Forces and Fields. INTRODUCTION. In Chapter 10, we learned that electric charges are the sources of electric fields and that other charges experience an electric force in those fields.The charges generating the field were assumed to be at rest, because if they weren"t, then another force field would have been generated in addition to the electric field.
