We discuss the possibility that the plasma trapped inside the solar magnetic loop region may be the principal arbitrator in deciding whether a given active region will release particles into the interplanetary medium or will remain a solely electromagnetic event. We analyze the particle abundance patterns and show that the particle selection occurs in a cool region much below the corona. We discuss the particle acceleration in time varying magnetic field and show that the betatron process can be very effective under solar conditions. We then show that the electron density in the flare region may be the critical parameter in deciding the evolution of the active region. Finally we show that direct observations of flares in the interplanetary medium agrees well with this suggestion.
