Magnets. How do they work? How does the number of coils affect electromagnetism? Hypothesis: When there is a flow of moving electrons‚ a magnetic field is created. We use the equation F = NIlB (Force = Number of coils x Current x Length of Wire x Magnetic Field Strength) to work out the magnetic force produced in a wire when there is an electric current present. Using this equation we can see that increasing the length of the wire (amount of coils) gives a larger force. So increasing the amount

without the worry. This applies greatly to the invention of the refrigerator. For decades people have been practicing inconvenient refrigeration techniques to prevent food spoilage but in 1834 Jacob Perkins built the first practical refrigerating machine through the ideas he encountered from other people. He modified the findings of Oliver Evans’s invention‚ the vapor-compression refrigeration and then built his idea of the refrigerator unit. Before Perkins development in 1834‚ ice was the only convenience

Chemistry Lab 9/5/2011 Avogadro’s Number Labs Abstract: Avogadro’s number was obtained using information based on the thickness of the stearic acid monolayer. Once mass was found‚ volume of the acid was obtained in both trials‚ .000076 cm^3 and .000068cm^3 respectively. Then area was calculated 214cm^2 and 230cm^2 respectively. Thickness could be calculated with that data and it came out to .00000036cm and .00000030cm respectively. By dividing the thickness by 18‚ the height of one carbon atom was
