It's called lava. Magma is formed in the magma chamber, then later when the volcano erupts, it turns to lava.
Lava and magma are both substances produced by volcanoes. There is a difference between the two, however. Specifically, magma has not yet come out of a volcano, while lava is magma that has erupted out of the cone.
