  We investigate electric and magnetic properties of graphene with rotationally
symmetric strain. The strain generates large pseudo magnetic field with
alternating sign in space, which forms a strongly confined quantum dot
connected to six chiral channels. The orbital magnetism, degeneracy, and
channel opening can be understood from the interplay between real and pseudo
magnetic field which have different parities under time reversal and mirror
reflection.
  While the orbital magnetic response of the confined state is diamagnetic, it
can be paramagnetic if there is an accidental degeneracy with opposite mirror
reflection parity.
