A good permanent magnet should produce a high magnetic field with a low mass, and should be stable against the influences which would demagnetize it. The desirable properties of such magnets are typically stated in terms of the remanence and coercivity of the magnet materials.

What metal is used in low melting alloys and magnets?
Several different metals can be used in magnets. Iron is perhaps the most common metal used in permanent magnets, but alloys such as Alnico (Aluminum, Nickel, and Cobalt) can also make very strong permanent magnets.
How are magnets used in guitars?
the pickups on an electric guitar are just magnets. they pickup the vibrations of the strings to make the sound. depending on the position and the magnets, the guitar will get different sounds.

Element used to make permanent magnets?
Iron, cobalt, and nickel are commonly used elements to make permanent magnets. These elements have magnetic properties that allow them to retain their magnetism over a long period of time.
Do the magnets in a television make the picture?
No. Or rather, it's a lot more complicated than that. Magnets are important in a cathode ray tube style television, but they don't "make the picture". The picture shows up as a result of an electron beam hitting the phosphor-covered inside of the tube. The magnets are used to steer the electron beam. In an LCD or LED type television, there are no magnets and an entirely different process is used.
