They do but it in the external magnetic field. In order for material to have magnetic properties without any fields it should be ferromagnetic. In paramagnetic all spins are pointed in the same direction. In diamagnetic spins are oriented randomly it vanishes the effect.
Your question is not perfectly clear. Soft iron for example does not support a permanent magnet condition.
But is may have a magnetic field induced in it by a magnet, and that field is of opposite polarity. This will cause it to be attracted to the magnet. These materials are considered paramagnetic.
And there are Diamagnetic materials in which a magnetic field is induced such as to be the same as the inducing field, and since it is of the same polarity, it will be repelled by the field.
And in your familiar 'rotating disk electric energy meter', eddy currents are induced into the aluminum (a material normally indifferent to a magnetic field) in such a way that it will rotate proportionate to the power being consumed.

No, aluminum is a non ferrous. Only ferrous metals can be attracted to a magnet.
the particles in the non magnetic material get magnetised, therefore it temporarily becomes a magnetic.
If you have a magnet, you can see if the magnet is attracted to the material in question.A diamagnetic substance can be identified by weak repulsion in the presence of a magnetic field.A non magnetic substance has no effect in the presence of a magnetic field provided the field is weak.Because if the field is strong enough the tiny electronic magnets may get rearranged so as to have an effect.
If you are talking about a non-magnet item then the item will become a magnet for a period of time. Changes in heat, how much it is used, or time can disable the magnet. Magnet!
Magnetic substances are those that are attracted to a magnet while non-magnetic substances are not attracted to a magnet.

The nail contains iron, which is ferromagnetic. Ferromagnets respond to a magnetic field (from a magnet) by generating their own magnetic field, ie, they become a magnet in the presence of a magnet. They also exhibit hysteresis, in that if they are exposed to a strong enough magnetic field, it will lock in and become a permanent magnet.

No. Aluminum is a non-magnetic metal.
No, a metal must have iron in it to attract a magnet.
MAGNETIC: Magnatite, Iron, Cobalt, Nickel, Manganese, Chromium. NON MAGNETIC: hydrogen, water, steel, graphite, diamond, silicon, carbon dioxide, methane, ethane, propane, and almost any other substance you can think of

Yes!
Electromagnets are non permanent magnets. They got magnetic field because of applied electric field. They lost their magnetic field which was around that, when the applied electric field is stopped. permanent magnets have magnetic property always with it. Permanent magnetic property loses when we heat the material. It cannot be regained once again. But electromagnets are capable of regaining its magnetic properties.
