Curved spacetime simulation
Adamtoons.de has some mind-blowing animations on gravitation as curved spacetime and relativity: movement, time dilation and length compression.

There’s also a charged ball simulation where you can create balls and observe their behavior under the influence of magnetic fields.
It’s worth a look, especially if you are struggling with physics concepts.
