What branch of electricity deals with the behavior and motion of electrons in a vacuum or special materials?
Vacuum electronics is the branch of electricity that deals with the behavior and motion of electrons in a vacuum or special materials, typically focusing on applications like vacuum tubes, cathode ray tubes, and traveling wave tubes. The study of electron behavior in these conditions is important for various high-power and high-frequency electronic applications.

Do blankets conduct electricity?
Blankets made of materials like cotton or fleece do not conduct electricity. However, metallic or electrically conductive materials, like metal fibers or wires, can be woven into blankets for special purposes, such as electric heated blankets.
Why are some materials attracted to magnets and others not?
Ferro magnetic materials (those attracted to magnets) have a special arrangement of their electrons which makes them susceptible to magnetic fields. Materials without this special electron structure are not affected my magnets or electric fields in the same way.
Why are halogen poor conductor of both heat and electricity?
Halogens have 7 valence electrons (electrons in their last shell), this means that they require one more electron to become stable (Octet rule). Electricity and heat are conducted when atoms share electrons by bonding (ionic, covalent, and metallic). Metals are good conductors of heat and electricity because they have free moving electrons. Halogens tend to keep their electrons since they have a -1 charge. As one electron is gained for the halogen atoms (diatomic) become stable, it conducts electricity and heat. However, the conduction of heat and electricity is poor because it barely reacts (only one electron reacts). Compare this to any other element which has a higher charge as (+2, -2, +3, -3, etc.), then the other element will conduct heat and electricity better than a halogen. This is because more electrons are shared / reacted, more conduction of electricity and heat (Heat and electricity are sometimes the result of electron movement, or that electrons carry heat and electricity). Note: A special case is an alkali metal which also has one electron to donate, therefore it has a +1 charge. Alkali metals still conduct electricity and heat because they have free moving electrons (delocalized in a sea of electrons moving freely even without reacting). Basically, metals have their own structure where all the electrons move around freely conducting electricity (therefore its an amazing conductor).
Is fibre is conductor or insulator?
Fiber refers to materials like glass or plastic that are typically insulators, meaning they do not conduct electricity. However, there are special types of fiber, like optical fibers, that can transmit light signals for telecommunications.
Why does passing a current through a wire create a magnet?
That is, basically, the way ALL magnets are created - by moving electric charges. In the case of a permanent magnet, it is mainly the electrons orbiting their atoms that produce this effect. As to the "why", the Special Theory of Relativity provides an answer, but it is fairly complicated. The summary paragraph on Wikipedia (article "Magnetism") says: "As a consequence of Einstein's theory of special relativity, electricity and magnetism are fundamentally interlinked. Both magnetism lacking electricity, and electricity without magnetism, are inconsistent with special relativity, due to such effects as length contraction, time dilation, and the fact that the magnetic force is velocity-dependent. However, when both electricity and magnetism are taken into account, the resulting theory (electromagnetism) is fully consistent with special relativity. ..." The Wikipedia article "Classical electromagnetism and special relativity" provides a more detailed explanation about the relationship between electricity and magnetism, according to the Special Theory of Relativity - but the math is a bit too complicated for my liking.
How is light absorbed and made into electricity?
light is absorbed by special cells known as photoelectric cells...... these cells are made uf certain materials that release electrons upon absorbing energy in the form of light...
What do electrons do to the nucleus?
Electrons orbits around the nucleus, which have neutrons and protons. When there is an imbalance of protons and electrons, it creates a static electricity. What I am trying to say is, nothing really special happens.
Why some materials are magnets and some are not magnet?
Ferro magnetic materials (those attracted to magnets) have a special arrangement of their electrons which makes them susceptible to magnetic fields. Materials without this special electron structure are not affected my magnets or electric fields in the same way.
Are there any non metal materials that conduct electricity?
I think there is one. The thing that is in pencils not lead it has a special name look it up.

What are nuclear materials?
Nuclear materials refer to substances that can undergo nuclear reactions, such as uranium and plutonium. These materials are used in nuclear power plants to generate electricity or in nuclear weapons for military purposes. Special precautions are needed in handling and storing nuclear materials due to their radioactive properties.
Why are some materials attracted to magnets and others not?

What is it that metals have that allow them to form their special metallic bonds?
Metal atoms are bonded each other with metallic bonds. A special feature in metallic bonds is the existence of 'pool of electrons'. It is responsible for the conductivity of electricity and heat in metals.
What are the special characteristics of materials?
Special characteristics of materials include conductivity (ability to conduct heat or electricity), magnetism (ability to be attracted to or repelled by a magnet), hardness (resistance to scratching or deformation), and ductility (ability to be stretched without breaking). These characteristics determine how a material can be used in various applications and industries.
How does copper and zinc conduct electricity?
All metals (copper included) form crystals that have the valance electrons in a free floating sea. They are not affiliate with any single atom and can move (fairly) freely between associated atoms. Shoving a charge in at one end of a wire therefore allows all the electrons to 'shove-over' and kick one out the other end.
What are the special reference materials?
special reference material
