The magnetic field of Mars is the magnetic field generated from Mars's interior. Today, Mars does not have a global magnetic field. However, Mars did power an early dynamo that produced a strong magnetic field 4 billion years ago, comparable to Earth's present surface field. After the early dynamo ceased, a weak late dynamo was reactivated (or ...
Strong magnetic stripes with alternating polarity run roughly E-W in the southern hemisphere, concentric with the south pole. [6] These magnetic anomalies are found in rocks dating from the first 500 million years in Mars’s history, indicating that an intrinsic magnetic field would have ceased to exist before the early Noachian. The magnetic ...
The dust in Gusev Crater is the same as dust all around the planet. All the dust was found to be magnetic. Moreover, Spirit found the magnetism was caused by the mineral magnetite, especially magnetite that contained the element titanium. One magnet was able to completely divert all dust hence all Martian dust is thought to be magnetic. [12]

In October 2018, Amazon unveiled the Fire TV Stick 4K, codenamed "Mantis," which "effectively replaces Amazon’s Fire TV pendant." [ 43 ] It is upgraded to a 1.7 GHz quad-core processor, 1.5 GB RAM, and supports 4K output, HDR10+ and Dolby Vision , Dolby Atmos, hardware-accelerated MPEG-2 decoding, and Miracast through a later update.

The Mars Observer spacecraft, also known as the Mars Geoscience/Climatology Orbiter, was a robotic space probe launched by NASA on September 25, 1992, to study the Martian surface, atmosphere, climate and magnetic field.
A new image of the black hole that lies at the center of our Milky Way galaxy shows that it is surrounded by a strong, twisting magnetic field.
The probe also found that Mars has no global magnetic field that would protect the planet from potentially life-threatening cosmic rays. The probe was able to calculate the atmospheric pressure on the planet to be about 0.6 kPa (compared to Earth's 101.3 kPa), meaning that liquid water could not exist on the planet's surface. [ 26 ]
