The coronal magnetic configuration of an active region typically evolves quietly for a few days before becoming suddenly eruptive and launching a coronal mass ejection (CME). The origin of the eruption is still under debate. The loss of equilibrium is one of the mechanisms that have been proposed to be responsible for sudden eruptions. The objectives of this paper are to discuss the contribution of flux cancellation mechanism in coronal mass ejections and to compare two possible mechanisms, viz., flux cancellation and breakout mechanism behind observed phenomenon.
