Molten core may explain Mercury's magnetic field

Mercury likely has a partly molten core, a new study indicates. This molten material may be generating the planet's weak magnetic field, whose existence has been a puzzle since its discovery more than 30 years ago.

some more info is getting in on one of the closest but also the less known planet in our solar system, in the coming years there will be more info as the probe ( don't know name) arrives there.

Just out of interest Mars has no magnetic field right ?
Please correct me if I am wrong. I'd like to know.

Yet the surface of mars shows evidence of volcanic activity true ?

And what of our Moon with evidence of historical basalt lava flows. I take it the Moon has no Magnetic field, so what about Venus and has anybody got some explanations ?

Mars has a very very weak magnetic field, Venus is a geologically active
planet, and has one the last time I checked, the Moon has none that I'm
aware of, though it does have an interesting phenomenon of pockets of
magnetism caused by the composition of certain areas.
