Virginia Tech PHYS 2306: Foundations of Physics II
PHYS 2306 continues Virginia Tech's calculus-based sequence into electricity and magnetism, covering fields, potential, circuits, magnetism, induction, and waves, with lab. It's required across engineering and the physical sciences after 2305.

What makes it hard
E&M is more abstract than mechanics: fields can't be seen, so everything rests on diagrams and vector math, and the intuition that carried students through 2305 has less to grab. The vector tools (flux, cross products, the right-hand rule) have to be fluent or every problem costs double.
What you'll cover
- • Electric fields and Gauss's law
- • Electric potential
- • Capacitance and DC circuits
- • Magnetic fields and forces
- • Electromagnetic induction
- • Waves and optics basics
The PHYS 2306 study guide
How to study for Virginia Tech PHYS 2306, step by step.
- 1
Make diagrams the default from day one
Field and force diagrams are E&M's equivalent of free-body diagrams. Nothing here is visible, so the representations are the territory. Draw them for every single problem.
- 2
Drill the vector tools until free
Cross products, flux, and the right-hand rule carry the course. If any of them costs thought, drill it now. Exam problems assume those tools are mentally free.
- 3
Learn Gauss's law as symmetry reasoning
The skill is choosing and justifying the Gaussian surface, not evaluating the integral. Practice explaining the choice out loud; the math that follows is usually the easy part.
- 4
Systematize circuit analysis
A fixed routine (label, simplify, apply Kirchhoff) survives exam pressure where inspiration doesn't. Circuits reward procedure; build yours early and use it every time.
- 5
Work cross-unit induction problems before the final
Faraday's law ties fields, flux, and circuits together and dominates late exams. Practice problems that span earlier units. That synthesis is standard final material.

FAQ
Is PHYS 2306 harder than PHYS 2305?
Most students find it more abstract: fields are invisible, so success rests on diagrams and vector math rather than physical intuition. Students who invest in the representational tools early generally find it no worse than 2305.
What math does PHYS 2306 need?
Solid single-variable calculus plus growing vector comfort: cross products, flux-style integrals, and the right-hand rule used constantly. Concurrent multivariable calculus is the comfortable pairing.
How do I study for E&M exams?
Draw field and force diagrams for everything, practice Gauss's-law symmetry choices out loud, and run circuits through a fixed procedure. Late in the course, work induction problems spanning multiple units, since that synthesis is what finals reward.
