They aren’t more powerful, just denser.

It’s the same magnetic field but now it’s focused into the size of a neutron star (roughly the size of Earth) rather than the size of a really massive start (much larger than our Sun, so millions of times larger than earth).

It’s spinning a lot faster and is still has a crazy density so even though it’s small, it has the mass for a large star, plus it’s spinning faster.

Magnetic fields are generated by moving charged particles, and neutron stars spin really fast. This is because they became so condensed when they were formed, so they started spinning faster. It’s like when a figure skater starts spinning with her leg out and then puts her leg down and suddenly is spinning super fast.
