Have you ever seen a levitating orb? A real orb just floating in the air. This is not some magic trick, it is science. To make the orb levitate you must first know about electricity and how it works. Static electricity is what causes it to levitate.
To understand how this electricity works we must start with the basics. The atom is the smallest unit of matter, consisting of protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Electric charges that are the same repel each other and charges that are different attract each other. Electric charges can exist alone, unlike magnetic poles.
Electric force is the attraction or repulsion between electric charges.

When the objects rub together electrons can move to the other object. Charging by conduction is the transfer of electrons by direct contact. Charging by induction is the movement of electrons to one part of an object that is caused by the electric field and second object.
To detect electric charge scientists use an electroscope. See figure 1. An electroscope consists of a metal rod with a knob and two thin metal leaves at the bottom. When the electroscope has no charge, the metal leaves hang straight down. When a charged object touches the knob the metals leaves repel each other.
Charges that build up as static electricity on an object do not stay there forever. Electrons like to move, returning to the object to its neutral state. When a negatively charged object and a positively charged object come together, electrons transfer until both objects have an equal charge. The loss of static electricity as electric charges transfer is called static discharge. Normally, a static discharge creates a spark. When electrons transfer between objects they heat the air around the path until it glows, which is the spark we see.
The fabrics that I am using are, a polyester blanket, my long hair and a cotton sweatshirt. Polyester tends to gain a negative charge and attract electrons. Human hair tends to give up electrons and gain a positive charge. I am also using a cotton sweatshirt and
In the article "Energy Story". I learned that electricity figures are everywhere and where electricity comes from. Did you know that electricity comes from atoms? atoms are the proton, the neutron, and the electron. Nevertheless, electrons contain negative charge, protons are positive and neutrons are neutral, I also learned that a charged atom is called an ion.
* Protons and electrons have equal and opposite electrical charges. Protons are positively charged, and electrons are negatively charged.
This is where electrons are transferred from one ion to another, so there is an electrostatic force between the ions. Variables involved: For this experiment I would expect to have 3 different variables, Independent, Dependent, and fixed variables, which all helps me to plan and explain the experiment thoroughly. The Independent variable, the thing that I will be changing in this experiment into the combustion of a range of alcohols, they will be four different alcohols, Methanol, Ethanol, Propanol, and Pentanol, which will help me to investigate combustion of different alcohols.
In paragraph two, it states "Pure water contains very few ions, so it does not conduct electricity well. When table salt is dissolved in water, the solution conducts very well, because the solutions contain ions.". In paragraph four, it explains how laundry ammonia can conduct electricity. It states "When ammonia dissolves in water, it reacts with the water and forms a few ions.". In conclusion, paragraph five explains more about how ammonia can cause electricity when it is put into a solution with vinegar.
The cause of static electricity is when there is an unbalanced molecular construction or non conductive insulators such as plastic, glass, ceramics, and other non conductive materials
An electric current exists when there is a net flow of charge through a given area. Electrons flow from the negatively charged region to the positively charged region. This is usually accomplished by using an electrical conductor which allows the electrons to pass freely through the material (Serway, et al. 709). This flow of electrons can generate heat when collisions between the molecules and electrons occur. These collisions then cause the molecules to break apart thus releasing heat. Some common examples of electrical energy are lightning, static electricity, and wiring outlets (Coleman, et al. 82). For the wildland firefighter, lightning is probably the
In the last article "Conducting Solutions" the main purpose is that it explains how different materials conduct electricity. In this passage, they describe an experiment with sugar and water. It says that when sugar is dissolved in water, the solution does not conduct electricity because there are no ions in the solution. It also describes experiments with vinegar and ammonia. It says that they work well as a mixture because the ammonia reacts with the acid in vinegar and hey form a lot of
When combing your hair, you scuff electrons from your hair onto the comb. Is your hair then positively or negatively charged? How about the comb?
The electrons move because they experience a electric current force in the wire. The battery causes an electric field and the electrons experience a force due to that field. The current flows in the opposite direction of the electrons and the flow of the
It starts with subatomic particles, such as protons and electrons, produce electrical fields. These relating electrical fields are composed primarily of electrons,
p>Many throughout the world who have been known to levitate have clearly possessed vehement states of mind. Levitation is the rising of the human body by metaphysical means and is believed to be the result of a supernatural force from psychic power or spiritual energy. In the early days, religious zealots such as the Christian Church assumed levitation was a clear indicator of a demonic possession. Although, it is a common factor among the possessed, many holy people have been known to levitate as well. The most prominent practitioner of levitation was most likely St Joseph of Cupertino, who was born in 1603 in Italy. It is documented that he levitated hundreds of times in his life and for extended periods of up to one hour or more. He is said to have achieved this by
An electricity and magnetism phenomenon apparently unrelated to power are electrical magnetic fields. We are familiar with these forces through the interaction of compasses with the earth's magnetic field, or through fridge magnets or magnets on children's toys. Magnetic forces are explained in terms very similar to those used for electric forces:
Over time, the charge accumulated on a powder surface will partly decay (dissipate) (Malave-Lopez and Peleg, 1985). Charge decay is a complex phenomenon that has been measured by different techniques (Paasi et al., 2001). The timescale for electrostatic charge decay is an important factor. For example, there will be a higher probability of considerable charge build-up on the material when charge decay occurs slowly. The charge decay rate is a measure of the rate at which the electrostatic charge present on the surface of a material can migrate away (Chubb, 2002). The charge decay rate is dependent on many factors, including material’s electrical resistivity, the resistivity of the other material on contact, RH of the surrounding air and hold time (Bailey, 1993; Sharma et al., 2001a). The lower the material electron conductivity the longer the time needed for charge decay. A powder in contact with a conductive material will dissipate the charge quicker than the same powder in contact with an insulator. It is anticipated that moisture adsorption will make the material more conductive. (Paasi et al., 2001) showed the charge decay rate to increase with increasing RH due to a concurrent decrease in surface resistivity. The hold time (defined as the time passed between the end of processing and dispensing the sample into the Faraday cup for charge measurement) was shown as the most effective option of dissipating charge following blending (Engers et al., 2006).
Now we will move onto other materials that are involved with electronics. The next group of materials that will be discussed are insulators. An insulator is a material that does not conduct electricity at all but will resist or stop it from traveling further. An insulating atom has eight electrons in its valance shell which makes this shell complete. Eight is the most electrons that any atoms can have in their valance shell this is why these are called insulators, no more electrons can fit in the valance shell of these atoms.
