Magnetic fields loop continuously without ever ending

HERE’S THE INTERESTING PART

Unlike gravitational lines that just pull straight in, magnetic fields are eternal loops. A field line exiting the north pole must perfectly curve around and re-enter the south pole, completing an endless circuit. They form incredibly elegant, invisible donuts of force that absolutely refuse to have a definitive starting or stopping point.
