Expert Answer:

There is no possible remote way.
However what we usually do is we see its influence on other nearby heavenly body like a passing comet or electron shower over it by a nearby star.
The later way gives us the most accurate idea of the planets magnetic field due to obvious reasons but for say the foemer way u might ask how do we know about the mearby body's composition and we know that by its spectral signature. I.e by studying the waves emitted or reflected by that body
