I guess it depends what level you're doing it at. I remember in year 9 my physics teacher spent 2 hours trying to explain electromagnetism only to receive blank looks from the entire class.
Personally electricity has always confused me... there's so many different aspects of it - current, charge, voltage, resistance, power, energy, all that lot.
We're starting quantum physics in a couple of weeks, not sure if I'm looking forward to it or not. Sounds interesting but it seems to me as if nobody actually understands it and it's all a bit crazy. That said, I don't really know anything about it yet. I've heard about Schrodginer's cat and that makes some sort of sense to me....

There are quite a few unsolved problems in physics. The one currently getting the most attention is the search for a theory which unifies Newton/Maxwell, Einstein, and Heisenberg. Classical physics, relativity, and quantum physics. Gravity is the hardest piece of the puzzle. Superstring theory, M-brane theory, and quantum gravity are the main current approaches.
Then there are the ones which usually aren't talked about. Like, why? Why is there a gravitational attraction between masses? And then there's origin. Choose your favorite big bang theories. Once you get back to an extremely dense collection of mass and/or energy, where did that come from? The best explanation is that God created it. Anything else proposed is just grasping at straws to avoid that explanation.

a sprint less difficult than the others are very intesting. the relationship between nature and physics, how nature has inspired physics. Leonardo da Vinci could desire to be the concentration of the presentation as his artwork became basically approximately a hundred% in accordance with observations from the organic worldwide around him. If that would not intrest you the subject remember is great another ideas could desire to contain: -Catseyes -Ornithopter -Radar -RAF flying greater healthful -Dreamer greater healthful wish this has helped :)

At my school, electricity and magnetism and quantum mechanics are the 2 that generally give people the most problems.

All topics are difficult unless you know them how to do them!!

Richard Feynman said "If you think you understand quantum theory, you don't understand quantum theory."
So I guess quantum theory must be up there.
