FSU PHY 2049: General Physics B
PHY 2049 (usually as PHY 2049C with the lab folded in) is the second semester of FSU's calculus-based sequence: electricity and magnetism, circuits, and optics. It's required for the same physics, chemistry, and engineering-bound population as PHY 2048, and most students rate it the harder of the pair.

What makes it hard
E&M removes the intuition mechanics provided: nobody has bodily experience of flux or induced EMF, so the concepts must be built from math and field diagrams alone. The calculus also steps up, with surface and line integrals in the central laws, and sign conventions in induction problems are a precision tax collected on every exam.
What you'll cover
- • Electric fields and Gauss's law
- • Electric potential
- • Circuits: resistance and capacitance
- • Magnetic fields and forces
- • Electromagnetic induction
- • Optics
The PHY 2049 study guide
How to study for FSU PHY 2049, step by step.
- 1
Build intuition deliberately with field diagrams
E&M offers no everyday experience to lean on. Drawing field lines, flux surfaces, and force directions for every problem is how the missing intuition gets constructed.
- 2
Refresh the integral calculus before it's needed
Gauss's law and induction use surface and line integrals. Reviewing them the week before they appear keeps the physics lecture from doubling as a math lecture.
- 3
Make sign conventions a checklist item
Lenz's law directions and circuit sign errors are PHY 2049's signature point leak. Verify direction reasoning explicitly on every induction and circuit problem.
- 4
Keep mechanics-era habits running
Diagram first, principle named, volume beyond the assigned set: the 2048 playbook still applies, on material where winging it works even less.

FAQ
Is PHY 2049 harder than PHY 2048?
Most FSU students say yes: E&M is more abstract than mechanics, the calculus is heavier, and intuition has to be built from scratch. The work habits from 2048 still apply, but they need to be aimed at concepts you can't picture from daily life.
What should I review before PHY 2049?
Vector manipulation, MAC 2312 integration, and your own 2048 problem-solving ritual. Surface and line integrals show up inside the central laws, so meeting them as review rather than as news is a meaningful advantage.
How do I study for PHY 2049 exams?
Draw the fields on every problem, check direction reasoning explicitly, and keep problem volume high, because the exams test setup on unfamiliar configurations. Treat sign conventions as a formal checklist step, since that's where prepared students still bleed points.
More FSU courses
PHY 2048: General Physics A
PHY 2048 (commonly taken as PHY 2048C, which folds in the lab) is FSU's calculus-based mechanics course covering kinematics, Newton's laws, energy, momentum, rotation, and oscillations, required for physics, chemistry, and students headed to the FAMU-FSU College of Engineering. It's the first course in the calculus-based sequence and a famous early checkpoint.
PHY 2053: College Physics A
PHY 2053 (typically PHY 2053C with integrated lab) is FSU's algebra-based physics covering mechanics, energy, and related topics without calculus, serving pre-health, biology, and other science majors whose programs don't require the calculus-based sequence. It's a standard MCAT-foundation course for FSU's pre-med population.
