What are metals that are attracted to magnets or made into magnets called?
Unpaired electons (which is to say, electrons not paired with another electron of opposite spin).
How is a electro magnet different from a regular bar magnet?
Br magnets and other permanent magnets is formed out of material that creates a and sustains its own magnetic field that is always in effect. These permanent magnetic fields are due to complex interactions of the electrons of the object and the way in which they spin. They are usually made out of paramagnetic materials which have unpaired electron spins in certain orbitals. In the case of permanent magnets, these unpaired spins align to create a ferromagnetic material which exhibits typical magnetic properties. Electromagnets on the other hand require manipulation of moving electrons in electrical current as opposed to in an atom. According to Biot-Savart whenever there is an electric field, a perpendicular magnetic field is generated. Normally, the magnetic field is weak in comparison, but by aligning the electric field in special ways you can amplify the magnetic field, and you can also increase the magnetic field by applying an even stronger current.
What do permanent magnets contain?
Permanent magnets contain magnetic atoms (almost always iron) whose magnetic poles are all (or mostly) aligned in the same direction.
What magnets are made from materials which retain their magnetic properties for a long time?
Permanent magnets.
What causes a magnetic field to be set up around a wire?
Passing an electric current through a wire will produce an external magnetic field. This is because the electrons have spin and this spin is what produces the field. Spinning electrons (of certain characteristics) also produce the magnetic field of permanent magnets. And no spinning electrons, no magnetic field.
What are the types of magnets?
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
What kind magnets are made from materials which retain their magnetic properties for a long time?
Permanent magnets.
How do magnets work naturally?
Natural magnets, such as lodestones, have a permanent and persistence magnetic field. These permanent magnets can also temporarily magnetize material such as iron, nickel, and cobalt.
What distinguishes a permanent magnet from a temporary magnet?
Permanent magnets do not lose their magnetic ability. Temporary magnets, however, gain magnetic properties when they are touched or moved by a permanent magnet. The properties of a temporary magnet dissipates over time after the permanent magnet is removed.
Which of the following is true of permanent magnets?
They are difficult to magnetize,
Are magnets made from certain materials?
ALL magnets are the result of moving electrons. A simple copper coil carrying an electric current demonstrates the simplest form.Permanent magnets are those materials in which a number of the electrons share a similar spin.Commonly reference is made to the magnetic loops of plasma on the surface of the Sun, but at a temperature of over 50 000 deg C, there are no magnetic materials. These magnetic fields are the result of electric currents flowing near the surface of the sun.The magnetic field of the Earth is generated by electric currents flowing roughly parallel with the equator. or rather, the net result of many electric currents flowing around the Earth - probably in the magma.But the ordinary permanent magnets are indeed made of particular elements in which the 'magnetic domains' may be aligned in parallel.
What is the different electromagnets and permanent magnet?
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.
