No common English word rhymes exactly with ˈmæɡmə. Words ending in -gma (dogma, stigma, enigma, sigma) share only the unstressed final /ɡmə/ and have a different stressed vowel, so they are not true rhymes. Magnum and magnet look similar at the start (mag-) but continue with /n/ or /nət/, not /mə/.
