True.
The magnetic poles move constantly.
False. The Earth's magnetic fields are constantly shifting, and have been at widely different points over the Earth's history. The North Pole (geographic) is defined by the Earth's spin, and does not appreciably change over millions of years.
False. Magnetic field lines curve out from one pole, travel through the surrounding space, and then re-enter the magnet at the opposite pole.
It is true that materials that exert magnetic forces are considered magnets. This is the case since it shows they have magnetic field lines that may have been induced or were naturally present in the materials.
It is false that a meter is exactly 3 ft. 1 ft = 0.3048 m (exactly) → 1 m = 1/0.3048 ft ≈ 3.28 ft ≈ 3 ft 3.37 in. 3 ft = 3 × 0.3048 = 0.9144 m (exactly)
False. Magnetic field lines emerge from the north pole of a magnet and curve around to enter the south pole, forming closed loops. They do not return to the same pole but rather connect the two poles, indicating the direction of the magnetic field.
False. The Earth's magnetic fields are constantly shifting, and have been at widely different points over the Earth's history. The North Pole (geographic) is defined by the Earth's spin, and does not appreciably change over millions of years.
False. Magnetic poles and domains are different concepts. Magnetic poles refer to the regions of a magnet where the magnetic force is concentrated, while domains are regions within a magnetic material where the magnetic moments of atoms are aligned in the same direction.

Invalid is not exactly either. It means that something is not applicable - that it will not hold up to a logical examination. It's closer to false but it doesn't exactly mean false.

False. Magnetic force and gravitational force are two distinct types of forces. Gravitational force is the force of attraction between objects due to their mass, while magnetic force is the force between magnets or between a magnet and a magnetic material.
False. Magnetic field lines curve out from one pole, travel through the surrounding space, and then re-enter the magnet at the opposite pole.
False
Yes most materials have weak magnetic properties
