yes, almost all, if not all of them do. i think every planet in our solar system has an iron or metallic core. this is what makes the magnetic field.

I know the moon and Mercury have small magnet field. Here is what my first source says about mercury.
Astronomers have discovered additional data that implies that Mercury is made mostly of iron and rock. Mercury has a feeble magnetic field.
The second source says that magnitism is in all the planets:
The Sun and most of the planets in our solar system have magnetic fields, so they can be considered magnets. The planet Mars probably has iron deposits which are magnetized. I would assume there are other planets in the universe with similar minerals.
Earths magnetic core happend because our molten core is iron. (see the third source) The greater the molten core of iron, the greater the magnetic core.

Every planet has a magnetic field, but its the size of the planet that determines its magnetic amplitude. Plus, earth has an atmosphere and two magnetic poles, so earth has a big magnetic field.

Not all of the but some do I know for sure that Jupier has a huge magntic field, i think the other gas giants do to & the only rockplanets with magnetic fields (i think) R Venus & Earth

every single planet with a molten iron (or partially iron) core has a magnetic field. this is due the huge amounts of iron going around much like an electromagnet. The hotter and larger the inside of a planet the higher the magnetic field

Not only do other planets have a magnetic field, but other moons have them as well.
