Erayga "diamagnet" waxa loola jeedaa shay ama walax muujisa hanti birlabeed daciif ah marka la dhigo goob birlabeed ah. Si ka duwan maaddooyinka paramagnetic, kuwaas oo si daciif ah loogu soo jiito goobta birlabeedka, qalabka diamagnetic waxaa si liidata u celinaya goobta birlabeedka. Saamayntani waxay sabab u tahay abuurista magnetic field ee jihada ka soo horjeeda goobta magnetic dibadda, taas oo keenta xoog saafi ah. Tusaalooyinka qalabka diamagnetic waxaa ka mid ah naxaasta, qalinka, dahabka, iyo garaafka. Erayga "diamagnetism" waxa uu tilmaamayaa ifafaalaha walxaha diamagnetic ee muujinaya naceybka daciifka ah ee goobta birlabeedka dibadda ah.
