From Wikipedia, the free encyclopedia
Original - A loop of wire (black), carrying a current, creates a magnetic field (blue). When the wire is reflected in a mirror (dotted line), the magnetic field it generates is not reflected in the mirror: Instead, it is reflected and reversed. The position of the wire and its current are (polar) vectors, but the magnetic field is a pseudovector.[1]
Reason
It is an excellent demonstration for how a pseudovector behaves differently from a vector under improper rotation. This example would be clear for anyone with a basic (year 12) understanding of magnetism. The direction of the B field is dependant on the direction the current flows through the loop. Rotating a loop about 180 degrees does not change the B field direction. Mirroring the loop on the same axis causes the current to flow in the opposite direction, inverting the B field produced.
