The attraction that develops between a polar molecule and a non-polar particle is called dipole-induced dipole attraction and depends on the concept of induction.
In this case the negative end of a polar molecule gets close to a non-polar particle (NPP in this diagram).
and since the negative charge repels the electrons in the non-polar particle, it induces a polar-like charge separation.
They can then attract.
This attraction is called a dipole-induced dipole attraction, because the dipole (the polar molecule) induces (forces) the non-polar particle to behave as a dipole.
This attraction can, of course, also happen with the positive end of a polar molecule which will attract (rather than repel) the electrons of the non-polar particle.
Leading, again, to a dipole-induced dipole attraction.
