Why do transition metals have magnetic properties?
Transition metals have magnetic properties because they have unpaired electrons in their d-orbitals. These unpaired electrons can align their spins in response to an external magnetic field, which leads to the generation of a magnetic field. This property is responsible for the magnetic behavior of transition metals.
Why does iron become magnetised?
The magnet, in this case, will induce magnetism in the iron. The iron has lots of tiny areas that are magnetic, but normally point in random directions; placing a magnet nearby will allign those, and thus induce the magnetism.
What is so special about a valence electron?
Valence electrons are the electrons in the outermost shell of an atom. These electrons are important in bonding and magnetism. For example, carbon has 4 valence electrons. It can make 4 covalent bonds to fulfill the octet rule. Also, if an atom has unpaired electrons, it is called paramagnetic and if an external magnetic field is applied, it will be attracted. If all of the electrons are paired, it is diamagnetic and will be repelled by an external magnetic field.
Does magnesium have magnetism?
No, it is not. Magnesium has no unpaired electrons. To be magnetic, a metal must have at least one unpaired electron (i.e., a spin up electron without a corresponding spin down electron). In general, response to a magnetic field is a property of electron spin.
What can you conclude about the orientation of the beam relative to the magnetic field when a beam of electrons passes through a magnetic field without being deflected?
That the beam of electrons were parallel with that of the magnetic field lines.
How do paired electrons affect the magnetic properties of a material?
Because of a property called spin, electrons act like tiny magnets. Most of the time paired electrons contain opposite spins, meaning the material has a weak magnetic field. The more paired electrons a material has, the weaker the magnetic field in the material. Unpaired electrons attract and repel other material. This determines which materials unpaired electrons match up with and attract to form a magnetic domain.
Differences between diamagnetism and paramagnetism?
diamagnetic has paired electrons as a result it repels for the magnetic field but,paramagnetic has unpaired electrons as a result it attracts tyhe magnetic field

Is phosphours magnatic?
Any atom with unpaired electrons in it's orbital exhibits paramagnetism, that is that it will be attracted into an inducing magnetic field. Phosphorous has 15 electrons: 1s>2e-(all paired) 2s>2e- 2p>6e-(all paired) 3s>2e-(these two are paired) 3p>3e-(note that these are the unpaired electrons that cause it to be paramagnetic) All this is because a moving negative charge produces a magnetic field if there are two electrons in the same orbital they always spin in opposite directions cancelling each other out. When there are unpaired electrons that creates the magnetic field.
Is oh diamagnetic or paramagnetic?
Diamagnetic metals have a very weak and negative susceptibility to magnetic fields. Diamagnetic materials are slightly repelled by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Diamagnetic materials are solids with all paired electron resulting in no permanent net magnetic moment per atom. Diamagnetic properties arise from the realignment of the electron orbits under the influence of an external magnetic field. Most elements in the periodic table, including copper, silver, and gold, are diamagnetic. Paramagnetic metals have a small and positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons, and from the realignment of the electron orbits caused by the external magnetic field. Paramagnetic materials include magnesium, molybdenum, lithium, and tantalum. Ferromagnetic materials have a large and positive susceptibility to an external magnetic field. They exhibit a strong attraction to magnetic fields and are able to retain their magnetic properties after the external field has been removed. Ferromagnetic materials have some unpaired electrons so their atoms have a net magnetic moment. They get their strong magnetic properties due to the presence of magnetic domains.
What causes an object to become a magnet?
All magnets are caused by the movement of electrons. No moving electrons = no magnet.In a permanent magnet, several adjacent electrons have the same spin - they form a magnetic domain.An electric current flowing in a circuit will form an electromagnet.A.In a permanent magnet, the origin of the magnetic field comes down to an unpaired electron in one or more of the orbitals (electron shells) of the atoms in the material. All electrons produce magnetic fields due to either momentum or spin. Spin is the property primarily responsible for the magnetic field in a permanent magnet. The Pauli exclusion principle requires that electrons occupying the same orbital be paired with electrons with opposite spin, and so the forces normally cancel each other out. An orbital with an unpaired electron means that its force will not be canceled and the atom will have an appreciable net magnetic field. The atoms in a molecule of iron, cobalt, or nickle all have unpaired electrons, which is why those materials are used to make strong magnets.Inducing or running a directional current through a block of one of these materials will align the magnetic fields of the atoms. When the current is turned off, the atoms remain oriented and the material is said to be magnetized. To be clear, the molecules in the material were always "magnetized". It is only the alignment that matters.
Does Magnetic forces act when electrons move?
Yes. To be more accurate, a magnetic field is caused whenever there are moving electrical charges. Even the magnetic field in a permanent magnet are caused by more electrons moving around their atoms in one direction, than in the other.Yes.

what is responsible for electricity?
Electricity is the movement of electrons between atoms. It is inexorably linked to magnetism (and light) - moving electrons create a magnetic field and a magnetic field will cause electrons to move in a conductor and when electrons lose energy light is created.
What causes some substance to be magnetic while others are not?
The presence of unpaired electrons that are aligned. This is the basis of the "everyday" magnetism that we experience with say fridge magnets. Technically called ferromagnetism in typical iron magnet.There are other materials which respond weakly to a magnetic field these are paramagnetic materials that have unpaired electrons that are not aligned. There also diamagneticmaterials repelled by a magnetic field - these forces are very weak, and this the norm for materials with no unpaired electrons.Some articles about magnetism on the web are very heavy going- particularly wikipedia.
