>>12370680>no, it really doesn't
I know that it REALLY doesn't and that magnetism is a relativistic phenomenon>it's like the first example you can give that instantly breaks the 3rd law
more like the only example studied in elementary non-relativistic mechanics that breaks it, because again it's a relativistic phenomenon>biot-savart only applies to situations where the divergence of current is zero (steady currents). that is a highly specialized case
which is what we have here, permanent magnets have no current sources>you fundamentally have to attribute energy and momentum to the fields to recover things like momentum conservation (which in elementary mechanics is tied to the 3rd law).
do you really think somebody who struggles to understand this shit and gets baited in this thread will get all this shit you're saying? You have to take college level EM to start talking about the stress-energy tensor etc. for it not to sound like gobbledygook.
