  • We don’t have sensors to directly sense a single magnetic field, but if you’ve played with magnets a lot, you can definitely “feel” how their forces work and develop kind of an intuitive physical sense.

    Perhaps a good example/analogy of something we can feel and understand somewhat intuitively but actually do not scientifically understand is gravity. You can definitely feel its effects / force, even though you don’t have a specific gravitational field sensor in your body per say.

    We have very good theories and formulas for calculating gravitational effects, but we still fundamentally do not understand what causes it.
