An electric current produces a?
An electric current can be produced in several ways. The most fundamental is to move a conductor, like a coil of wire, in a magnetic field. This is the basis of generation in rotating machines. You can produce a current in a conductor by connecting opposite ends to the + and - poles of a battery, but don't try this with your car battery or you will burn out the conductor and produce a lot of heat. It is safer to use a small dry battery. You should work out the current which will be obtained using Ohms Law, and use an appropriate resistance to limit the current. This of course is using chemical energy that has been stored in the battery.
Is there a limit to how strongly magnetised an iron nail can get?
Yes, every material has its limit in this respect.
What is the saturation of a permanent magnet?
Saturation is an effect by which any increase in mangetising force produces a feable improvement in magnetic property if the magnetising force is increased beyond a certain limit. This is analogous to the stress-strain curve of a material obeying Hooke's law. Saturation is of serious concern in electrical engineering that when a Current transformer with a certain ampere rating is fed from a high current source at primary(than it can carry) , the unit can respond at secondary upto the max. magnetic flux carrying capacity of the core and if at such a condition, the secondary if kept open, can produce an unopposed m.m.f which would consequently produce heating of the core and in some cases to the exploding of the CT unit. The classical equation that relates magnetism with electricity is H x l= NI which can be used for theoretical calculation of mangetic field intensity with a given ampere turn. However, saturation for an artificial permanent magnet is the max. value of H upto which is can be magnetised, in spite of being exposed to a strong magnetic field for a specific duration.

What is Difference between elastic limit and proportional limit?
Proportionality limit is the point upto which the stress remains directly proportional to strain whereas elastic limit is the point upto which the material remains elastic ie. if the stress is removed within elastic limit, then the material will regain its original shape and size.

Why is the Earth's core magnetic if its temperature is above the level at which metal is magnetic?
Moving electrical currents do NOT have an upper temperature limit. You're thinking if permanent magnets.
What type of metal can repel a magnet?
All metals can repel a magnet. The degree to which they do so is dependent on whether they are ferromagnetic, paramagnetic, or diamagnetic.A ferromagnetic metal is one which has a magnetic field regardless of whether or not they are subjected to an applied or external magnetic field. These are often called permanent magnets. The strength of their magnetic field varies depending on the strength of the external magnetic field, but has a limit outside of the external field. Iron is an example of a ferromagnetic metal.A paramagnetic metal is one which has a magnetic field only when subjected to an applied or external magnetic field. The strength of a paramagnetic metal's magnetic field tends to vary proportionally with the external magnetic field, and so these are often the strongest magnets that we see. An electromagnet is the easiest way to conceptualize the way a paramagnetic metal works. When an electromagnetic circuit is turned on, it's a magnet, when it's turned off, it's not. Tungsten is an example of a paramagnetic metal.Diamagnetism is a property of all materials, not just metals. This property is kind of hard to explain classically, so just think of it as a material's magnetic field created, when subjected to an external magnetic field, because of all of the material's electrons being pulled one way, and all of the material's protons being pushed the other way. The strength of a magnetic field from a purely diamagnetic material is farweaker than that of a paramagnetic or ferromagnetic material's magnetic field.
