Quel est l’impact de la présence d’un champ magnétique sur la capacité d’une planète à maintenir la vie ?<end_of_turn>
<start_of_turn>model
A planet's magnetic field plays a crucial role in its potential to sustain life. The magnetic field acts as a protective shield, deflecting harmful solar radiation and cosmic rays. Without this protective barrier, a planet's atmosphere can be gradually stripped away by solar winds, leading to the loss of essential gases like oxygen and water vapor. For instance, Mars, which lacks a strong global magnetic field, has a much thinner atmosphere compared to Earth. Thus, a magnetic field not only preserves the atmosphere but also creates a more stable environment, increasing the likelihood of life's sustainability.<end_of_turn><eos>
