no mars magnetic field is not strong because it is far away from the sun than earth.
A strong magnetic field has a higher magnetic flux density than a weak magnetic field. This means that a strong magnetic field exerts a greater force on nearby magnetic materials compared to a weak magnetic field. Additionally, strong magnetic fields are more effective for magnetizing materials or creating magnetic induction.
A magnetic field is caused by the internal motion of molten rock in the outer layer of a planet's core. Mars is smaller than the Earth, so it's core has cooled down to the point where the magnetic field has all but shut down.
The dynamo. For terrestrial planets, the dynamo is a molten core of nickel-iron. Mercury and Earth have fairly strong dynamos and therefore fairly strong magnetic fields. Venus and Mars do not, and have only weak magnetic fields.
Mercury is the planet that has craters, cliffs, and a weak magnetic field. Its surface is heavily cratered, and there are large cliffs called scarps. Mercury's magnetic field is about 1% as strong as Earth's magnetic field.
The planet known for being covered in cliffs and craters and having a weak magnetic field is Mercury. It is the closest planet to the Sun and has a surface marked by extensive impact craters due to its lack of a significant atmosphere. Mercury's weak magnetic field is a result of its small size and slow rotation, which limits its ability to generate a strong dynamo effect.
Mars has a very weak magnetic field compared to Earth. It is thought to be a remnant from when the planet had a more active core. This weak magnetic field is not strong enough to provide the level of protection from solar radiation that Earth's magnetic field offers.

Mercury fits this description, as it has craters, cliffs (known as scarps), and a weak magnetic field. Mercury's magnetic field is only about 1% as strong as Earth's magnetic field.

coz if you try to attract a weak and a weak side it wont stick. same with the strong and strong side. But if you put a strong side next to a weak side it will attach. When a strong magnet is brought nearby the domains line up more closely with the magnetic field. The result of this reorientation is an overall magnetization of the weaker magnet.
Mars no longer has a magnetic field. Look at earth for a moment. The earth's magnetic field is generally thought to be the product of dynamo action associated with motion (currents) in the molten fluid core of the earth. Other planets that have magnetic fields are, in general, thought to have this same or a similar source for their fields. Mars no longer has a molten core. Our studies have revealed that there are parts of the crust of Mars that have been magnetized. We see that these areas have a residual magnetic field that has been left as an "impression" of the original magnetic field of the red planet. And that field has changed polarity at different times over the period when Mars still actually had a natural magnetic field and it magnetized portions of the crust. A link to the Wikipedia article on Mars is provided.
Gold is not naturally magnetic, as it is a non-reactive metal. However, it can become weakly magnetic when exposed to a strong magnetic field, but this magnetism is usually very weak and temporary.
Auroras are interactions of the planet's magnetic field with the solar wind, exciting particles in the upper atmosphere. Mars' atmosphere is thin and its field weak, so such interactions as there may be would not be visible.
Mercury has a weak magnetic field, about 1% as strong as Earth's. Earth's magnetic field is generated by its outer core, which produces a powerful magnetic field that protects the planet from solar winds and cosmic radiation. Mercury's magnetic field is thought to be caused by its partially liquid core and is much weaker due to its smaller size and slower rotation.
Any electric current does generate a magnetic field, but it might be a very weak magnetic field that you would not notice. In order to create a powerful electromagnet, wire is wrapped around a ferromagnetic core, typically hundreds or thousands of times. Each coil of the wire adds to the magnetic field. But unless the current is extremely strong, a single straight wire produces a magnetic field that's quite weak, but it IS strong enough to deflect a nearby magnetic compass.
