Chemistry
Because the world is depleting resources, engineers and scientists must find a way to recycle energy, that is, renewable. In the engineering field, we try our best to recycle our materials to maximize efficiency and to minimize cost. There are lots of potential sources of energy that we, humans can harness. One is gravitational force. Is it possible to harness useful energy from gravity alone? How about the motion of the Earth wtr to the Sun? These are the type questions that will shape how we harness energy, and answers to these questions will indeed benefit the human race.
A carabao is useful because it helps farmers to plow the field.
The primary difference is that in materials that can be used as magnets, the atoms can form what are called magnetic domains. Individual atoms and small groups of them form these domains, and the domains can be caused to "face the same way" when exposed to a magnetic field. When the field that aligned them is removed, some of the domains don't return to their previous orientation. They stay aligned leaving a residual magnetic field. The materials that cannot be used magnets don't have magnetic domains. If you heat magnetic material and expose it to a strong magnetic field while it's hot (like at or above its Curie temperature), and then you apply a strong magnetic field and maintain the field while cooling it down, the field "impressed" on the material will largely stay there and you've made a permanent magnet.

No. A compass is a useful tool on Earth because the needle aligns with Earth's magnetic field and we know the shape of that field. There would be no such field in outer space.
1. first go to the recycle place and searchboth computers
They often have calculators on them
A compass has a magnet that points north, according to the Earth's magnetic field. It is useful, precisely, to find out where north is.A compass has a magnet that points north, according to the Earth's magnetic field.

i have no idea yes
d
in making machines
because they detect cancer .
