What exactly is a magnetic field?

Ask Science@lemmy.worldEnglish · 1 year ago

We know what causes magnetic fields and we know what their effects are, but what actually are they? What does it mean for them to be composed of “lines of force”? What is the mechanism of that force? What is actually going on in a magnetic field that the space outside of a magnetic field lacks?
