Earth’s magnetic field is vertical at the poles and horizontal at equatorial points. Hence no magnetic force (F = qν B sin 0°) acts on the charged particles reaching the poles, but force (F = qν B sin 90°) does act on the charged particles reaching the equator which deflects the particles sideways. Hence only high-energy cosmic ray particles are able to reach the equator, whereas even low-energy cosmic ray particles are able to reach magnetic poles.
