In eloquence there is magic explanation

Can someone explain this line: "In eloquence there is magic" from the hadith... Narrated Buraydah ibn al-Hasib (RadhiAllahu 'anhu), I heard the Prophet of Allah ﷺ say: > In eloquence there is magic, in knowledge ignorance, in poetry wisdom and in speech heaviness. I searched the net but I still cannot understand what it means. Does it mean people use magic to become eloquent?
