This paper reports the study of moving magnetic structures inferred from the observations of a moving type IV event with multiple sources. The ejection contains at least two moving radio emitting loops with different relative inclinations. The radio loops are located above multiple H-alpha flare loops in an active region near the limb. The relationship between the two systems of loops is investigated. The spatial, temporal, and geometrical associations between the radio emission and near surface activities suggest a scenario similar to coronal mass ejection (CME) events, although no CME observations exist for the present event. From the observed characteristics, it is found that the radio emission can be interpreted as Razin suppressed optically thin gyrosynchrotron emission from nonthermal particles of energy about 100 keV and density about 100-100,000/cu cm in a magnetic field not greater than 2 G.
