No not all metals are attracted by a magnet.iron,steel,nickle,and cobalt are some that are attracted to a magnet.

The answer is no, electromagnets do not attract all metals, rather they attract only some of the alloys that contain iron. So, steel and iron, But not all of them, (Stainless steel which contains iron is an exception)for example.

The metals which are not attracted to electromagnets include aluminium, copper, titanium,brass, bronze, tin, nickel, platinum, gold, silver, lead, pewter. Electomagnetics were first used in the early part of the twentieth century.

magnets themselves, were first discovered and used in the 19th century.
Electromagnets are used to lift heavy weights with a crane, in solenoids, electric motors, generators, transformers, and many other useful applications that are used in industry to make our world function.

Magnets inhabit our world in a million different ways.We use them to stick things on the fridge and to close the fridge door. We often forget the fun we had in science at school, picking up iron feelings and paper clips.

A type of magnet which the magnetic field is produced by the flow of which is an electric current.

Magnets attract things made of iron and steel. We know how a magnet can pick up nails or paper clips. But this is not an ordinary magnet. It is an electromagnet. It means it is operated by electricity. It is very strong and can be turned on and off. We know how can an electromagnet is made? The electromagnet works only when electricity flows through the wires. We know this because, when the wires are disconnected, we break the circuit. Then nails and coil can no longer pick up paper clips.

Our electromagnet is not very strong. However, by using many coils of wire and more electricity, an electromagnet can be made much stronger. It can be far more powerful than an ordinary magnet. Things that use electromagnets are telephones, tape, recorders, loudspeakers, cars, refrigerators, television, hair dryers and many other things that have motors in them.

No if you use a copper coin or a silver ring near a magnet, nothing happens. But if you put objects made of iron near a magnet, the magnet attracts them. Magnet attracts paper clips because they are made of steel, which is mostly, iron.

The basic idea that rests behind all electromagnets would be exceedingly simple: By running electric current all through a wire, a magnetic field can be created. The magnetic field will then disappear once the current ceases.

To give you an idea, the simplest form of a true electromagnet would be a coiled wire. An electromagnet basically begins with a battery (even other sources of power may be used) and a wire. If you attach a wire straight from the positive to the negative terminals of a typical D-cell, the electrons flows to the positive end rapidly and the battery quickly drains. Thus typically some sort of load (like a light bulb) is connected in the middle of your wire. A small magnetic field is thus generated.

A great deal stronger magnetic field may be obtained if a "core" of certain paramagnetic or ferromagnetic material (frequently soft iron) is positioned inside the coil. The current which in effect flows through a given wire results in a magnetic field which forms around the wire. This field is oriented as per the right-hand rule.
