We investigate in a potential model of independent quarks the {ital M}1 transitions among the low-lying vector ({ital V}) and pseudoscalar ({ital P}) mesons. We perform a static'' calculation of the partial decay widths of twelve possible {ital M}1 transitions such as {ital V}{r arrow}{ital P}{gamma} and {ital P}{r arrow}{ital V}{gamma} within the traditional picture of photon emission by a confined quark and/or antiquark. The model accounts well for the observed decay widths.
