She was a member of the Iberian Federation of Libertarian Youth and the Confederación Nacional del Trabajo (CNT), and served as interim secretary of Mujeres Libres.

[1] She became orphaned at a young age following the death of her mother, Dolores Gómez Soriano, a homemaker, and her father, José Magaña Rosa, a farm laborer.

Magaña organized the charitable International Antifascist Solidarity Festival at the Cervantes Theatre in Almería, and she visited anarchist militiamen on the front of Granada to bring them newspapers and food.

[2] Taking advantage of her work at the Librería Inglesa, Magaña, along with other antifascists led by Joaquín Villaespesa Quintana, undertook the task of translating and copying bulletins from the British BBC about World War II.

These were later distributed in Almería and Gibraltar through the antifranco publication El Campense, in support of the Allies in the war against Nazi Germany under Adolf Hitler.
