Question

Does mars have a planet-wide magnetic field?

Answer 1

Mars does not have a planet-wide magnetic field currently. It has regions of strong surface magnetization indicating a past global magnetic field, but the absence of a liquid conducting core means it cannot generate one today.

Step-by-step explanation:

No, Mars does not have a planet-wide magnetic field. However, observations made near Mars between 1998-2000 revealed that there are areas of strong surface magnetization on Mars, indicating that it may have had a global magnetic field billions of years ago.

Unlike Earth, which has a magnetic field generated by a circulating electric current in its liquid metallic core, Mars lacks such a feature today. This lack of a liquid material in Mars's core that would conduct electricity suggests the red planet cannot sustain a global magnetic field at present.

Answer 2

any object in space has a field, it's just the smaller it is the lower the force of that field. Two baseballs can be placed 1 meter apart and one of them if not both will pull the other twords it. This experiment was done on a simulation and it took 4 weeks for them to hit each other
