No. Not all meteorites contain the necessary Iron and/or Nickel, a combination of which is the magnetic medium contained in those meteors and meteorites (meteors which fall to Earth) that makes them able to hold a magnetic "field". I am not knowledgeable as to why tiny pieces of interplanetary rock and metal have a magnetic field, though. That is a cosmological question probably related to conditions during the beginnings of the Solar System.
The meteors and meteorites that are most common and not magnetized as a result of their lack of iron or nickel, are called "carbonaceous chondrites." They are stony but usually less massive than the Nickel/iron containing meteors and meteorites.
Interestingly, there is a sort of mathematical rule of thumb which indicates that for each, or any meteor of a given size, there are 3 more similar meteors/meteorites of smaller sizes. This is true from planetesimal size giants a thousand kilometers in diameter down to the grain sized particles in "rings" of material in what is thought to be a planetary "parking spot" between Mars and Jupiter. Usually referred to as the "asteroid belt"; it is often thought to be either the remnants of a planet which fell apart or of a planet that never formed.
Metorites
Metorites
Domains in magnetized materials are all aligned in one direction - those in un-magnetized objects are arranged randomly.
Domains in magnetized materials are all aligned in one direction - those in un-magnetized objects are arranged randomly.
When an object that is not magnetized becomes magnetized and all of the domains within the substace are aligned with the maget that it is attracted to.
Metorites and astroids.
it is because of of the area it was made in.
All materials are magnetized when placed in the magnetic field . The material magnetized by the effect of a magnetic field is called magnetic permeability.
Yes. All major bodies in the solar system have been hit by metorites. Mercury's surface is covered with impact craters.

Magnetization does not affect the mass of the material being magnetized. All the magnetizing field does is align the magnetic domains of the material being magnetized. No matter or mass is added, or "created out of energy" or the like. Nothing changes except the orientation of magnetic domains within the material being magnetized.
The magnetic domains of an unmagnetized material will be pointing in random directions, which is why it is appearing to me unmagnetized. In a magnetized material, they move from north to south.
