Magnet Activity Name. ____________________________________________ 1. Paper Clip magnet. Straighten a paper clip out. Tie a 7 inch tread to the middle of the clip. Drag a magnet the long length of, lift and return the magnet to the beginning end repeat the motion Repeat the motion till it becomes a compass. Why was the paper clip not a compass at first? Why did the clip turn into a compass? 2. Circle Magnet. Place the circle magnet on top of your desk. Take a hand magnet, put it under the desktop

difficult to measure the magnetic field of the earth quantitatively, due to there were no real standard to compare it against. Geologists in that era had difficulties on navigating from point A to point B [2]. As electromagnetic theory was industrialized through the 1800s, it was found that magnetic field strength could be given a definite value using coils which carries the current. In this EEi, the aim is to determine the measurement of the local magnetic field, comparing to a known value created

THE “COOKIE MONSTER” IS CREATED A BRIEF OVERVIEW OF MRS. FIELDS, INC. Mrs. Fields Cookies (MFC) is based in Broomfield, Colorado with a production and distribution facility in Salt Lake City, Utah. Debbi Fields and Randy Fields opened their first store in Palo Alto, California in 1977, and its first headquarters was in Palo Alto, California, moving soon thereafter to Salt Lake City in 1982. Between 1985 and 1988, the company opened 225 new stores. By the late 1980s the chain had grown to include

Introduction: Mankind has been aware of the presence of magnetism and electricity since ancient times. Prehistoric man observed instances of lightning and static electricity, as well even creating a primitive version of the compass. Magnetism wasn’t officially discovered until the late 16th Century, and it would be even longer until scientists learn to wield electricity for demonstrations in the 18th Century. Now, three-hundred years later, we are combining these two forces to enhance transportation

families in France. Throughout his life, he studied the fields of philosophy, literature, language, botany, chemistry, astronomy, and mathematics. The thing that he is most known for is developing Coulomb’s law, which described the electrostatic forces of attraction and repulsion. His law would serve to be very essential to the development of the theory of electromagnetism. The impact that his work had would go on to leave a legacy behind in the field of electromagnetism, geotechnical engineering, and

So, the total electric field at charge 1 is 1.91 N/C [N 45o E]. 34.a) Draw the FBD first, let up and right be positive. From the FBD, the charge 1 is at rest and have a net force of 0. F_T cos⁡40°+(-mg)=0 F_T=mg/(cos⁡40°) =(0.15)(9.8)/(cos⁡40°) =1.92 N So, the

kassegne@mail.sdsu.edu Abstract—Accurate and high throughput cell sorting enabling technology in molecular and cellular biology, biotechnology and medicine. We classify these technologies as either active or passive. Active systems generally use external fields (e.g., acoustic, electric, magnetic, and optical) to impose forces to displace cells for sorting, whereas passive systems use inertial forces, filters, and adhesion mechanisms to purify cell populations. Cell sorting on microchips provides numerous

the electric charge has an electric field. An electric field can only be created by a positive charge and destroyed by a negative charge(Brightstorm, 2010). According to Bob emery, owner of senior physics website, to generate electric power it requires motion between a magnetic field and a conductor. Attraction of a magnet is limited to certain boundaries this is called the magnetic field of a magnet (Makemegenius, 2013). An electric current in a magnetic field will experience a force, (HyperPhysics

Plate tectonic convergence at a rate of about 4 mm/year between the Eurasian and African. Plates dominates the straits of Gibraltar (Argus et al., 1989). The stratigraphic evolution of the sediment drifts is therefore greatly influenced by both regional tectonics and ocean circulation (Medialdea et al., 2009; Lopes et al., 2006; Terrinha et al., 2009; Zitellini et al., 2009). Coring results from Expedition 339 showed that initial contourite formation started at about 4.5 to 4.2 Ma ago with more

(science, technology, engineering and mathematics) is one of the most profound aspects of education today and it is moving the world forward in research. However, in the STEM occupations, there is a gender gap and underrepresentation of women in the field. For this research, the gender gap (with women) in STEM education/careers and how it can be reduced will be examined. Furthermore, it has been hypothesized if teachers encourage and support girls who want to go into STEM education, it will promote
