Magnetics - not magnets. These components (which do include some magnets, inside transformers) are used to isolate the network signals from the rest of the board, and to help with EMI suppression. By using a socket with integrated magnetics, the build cost of the R PI, and the board complexity, was reduced. However, the first batch of boards was built using normal sockets i.e. without integrated magnetics.
