In this talk I will review some
transport properties in Weyl semimetals that are connected to the geometrical
properties of the bandstructure in these systems, like the (now) famous B^2
dependent negative magnetoresistance, observed in these materials[1]. Within
this context, I will describe other transport and optical phenomena that were
supposed not to be allowed in these materials[2], like the linear magnetochiral
effect[3]. I will describe how this effect also allows for the presence of
second order non linear optical responses in inversion symmetric Dirac
semimetals under the presence of an external magnetic field[4].
