In which direction do charged particles bend in a magnetic field?

As a project, we are constructing a cloud chamber to detect positron trails. Positrons and electrons bend in the opposite direction when in a powerful magnetic field. Say, we construct parallel electromagnets on two opposite sides of the cloud chamber, and pass the current in the same direction for both of them, with respect to the North-South polarity within the chamber, which pole will the positron bend towards, and which pole will the electron bend towards?
