botany and zoology are on different sides of the science spectrum. He realized that he was not the first to discover this but Oersted did. Before Oersted’s experiment the relation between magnetism and electricity was ignored due to the “chemical and electrical phenomena exhibited by the wonderful combination of Volta, at that time almost entirely absorbed the attention of scientific men” (Davy 8). The idea that the two had any relation was overlooked by the scientific community of the…

Recent studies have shown that direct physical contact of the human body with the surface of the earth (grounding or earthing) produces profound quantifiable physiological effects. A reasonable hypothesis to explain the benefits is that a direct connection to the earth and the human body allows the abundance of free electrons to flow from the ground to the body. It is proposed that because there is sufficient evidence to suggest that earthing has positive effects on physical health, the influx…

In this equation, x and y denotes the number of moles of RE and Mn atoms per formula unit of the structure, respectively. The RE and Mn represent the theoretical magnetic moment of trivalent free RE3+ ions and divalent Mn2+ ions respectively. The experimental values of total magnetic moments were found to be smaller than the calculated values (Table xyz). The crystal field effects can lead to lower value of magnetic moments for RE3+ ions in these compositions as compared to free RE3+ ions,…

The Human Battery Do males or females produce the most electric current? Abstract The Human Battery Do males or females produce the most electric current? Abstract The purpose of this project was to determine whether males or females produce the most electric current. An aluminum plate, a copper plate, a micro ammeter, two lead wires with alligator clips, water, notebook paper, and pencil were used as materials. It was predicted that males would produce a greater electric…

Indeed, electrostatic phenomena are the sights we see most of the day. Some of us may have fun to rub a plastic ruler on our hands and then bring it closer to our friend's hair until it appears that a few strands of hair stood up because of it. Or try using a balloon, rub it into our hair and then stick it on the wall, see what happens? The balloon will stick to the wall. Or on a large scale electrostatic phenomena that you often see in an emergency because of lightning static load static…

The aim of this experiment was to build a shake torch and measure the electrical voltage produced when the magnet passes through a coil of wire. Our dependent variables were the amount of magnets (length of magnet) and the amount of shakes. This was done to help us discover if there was a relation between the amount of magnets, and the induced current produced. It was to investigate if a greater magnetic field and increased amount shakes would improve the shake torches ability to light the LED…

common in a wide variety of applications. However, electrodermal activity and the galvanic skin response are not commonly measured things in places such as the medical field, or education. Electrodermal activity (EDA) refers to the variation of the electrical properties of the skin in response to sweat secretion. (Benedek et al., 2010) Collecting this information is relevant in applications because of the use of testing emotional effects on physiological responses. According to Mark Handler and…

It modifies the electrical properties of substances such as silicon and germanium. Another benefit of boron for our modern technology is its use in neodymium magnets. These powerful magnets are an alloy of neodymium, iron and bron. The magnets used are found in computers…

The body is made up of many systems working together as a whole and the most significant one is the nervous system. The nervous system is responsible for making sure the rest of the body does what it needs and without this elaborate electrical system the body would have no meaning. There are many components to this beautiful labyrinth of nerves that allows us to be the marvelous humans we are. This system is complicated in itself but broken down into its peripheral, somatic, autonomic, and…

The purpose of the lab was to determine which unknown substances were ionic compounds, if any, using 4 different methods. This lab was to determine which of the three unknown substances (X, Y & Z) are ionic compounds and which are not ionic compounds. In conclusion unknown Y is an ionic compound and unknown X and Z are not ionic compounds. In order for a substance to be an ionic compound it must have a high melting point, it must be brittle, it must be soluble in water, it can not conduct…
