Because some alloys from other materiel wont stick to the magnet as well and steel can be magnetised easy so it could be heeps easyer to sort the steel from the alloy and other non metal materiel.(note the magnet will only pick up steel ,cobalt and nickel or things containing these in high levels).
Electromagnets only pick up strong metals.Steel is pretty strong.

Semi-metals or metalloids. The elements boron, silicon, germanium, arsenic, antimony, tellurium, and astatine have properties similar to both metals and non-metals. These elements are located along the semi-metal line of the periodic table.
Alkaline earth metals are in the second group. Be is the first metal of them.
Bronze is a metal. All metals conduct heat.
All alkaline earth metals and their salts are reactive and they have a blue-print that identifies them as an alkaline earth metal but metals exist as metals, and salts as salts, with different structural compounds.
Metal detectors work by emitting electromagnetic signals outward. When those electromagnetic signals bounce back to the receiver, the machine knows that there is an object in that location and alerts the user.
A junkyard electromagnetic crane simply seperates metal objects from the non-metals ones. This is to ease the workload of the workers from separating them manually.
an alloy is a mixture of metals and sulphur is a non metal so the answer is no . :) hope that was helpful
X-rays and gamma rays, although metals do absorb some of both.
There are many helpful and usefull metals that we use some of the most important metals aretintianiumaluminiumiron andcopper but these arej ust my favshope this helps
When light falls on a metal, its rapidly changing electromagnetic field induces similar motions in the more loosely etc.
If you are asking "How many metals are there," then no, there is approx. 95 metals.
A metal and a non metal. Two non metals. A metal and a metalloid.
Any metal that reacts with oxygen will produce a metal oxide. For example, magnesium reacts with oxygen to produce magnesium oxide, and zinc reacts with oxygen to produce zinc oxide. It is helpful to know the general word equation: metal + oxygen -> metal oxide
Magnestism in neither a metal or a non metal. Although metals tend to be magnetic while non metals ten not to be
