Electricity and Magnetism, or PHYS102.1x, serves as an introduction to electricity and magnetism following the standard second semester college physics sequence. It begins with electric charge in matter, the forces between charges, the electric field, Gauss’s Law, and the electric potential. Electric current and resistance are introduced, and then the course moves to the magnetic field, Ampere’s Law, and induction. PHYS102x consists of around 5 weekly learning sequences, each with ~1.5 hours of video lectures, conceptual lecture problems, and online homework questions. The course concludes with an online exam during the 6th week.
What textbook is required?
The course will not follow or make assignments from a specific textbook. Any relatively recent freshman physics textbook should suffice. We will suggest reading assignments based on topics. Contact us if you have a question about a specific textbook.
Is the class free?
Yes, although you are strongly encouraged to acquire a freshman physics textbook. You will also need a calculator capable of calculating exponents and trigonometric functions. You also have the option to add an edX Verified Certificate for $25.
Does the course cover circuits?
No. In order to reduce the length of the class from a full semester, we only cover electric and magnetic fields. We will discuss current, as needed for magnetic fields, and resistance.
