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

Marketing by Numbers Exercise Set One 1.1 Sanborn‚ a manufacturer of electric roof vents‚ realizes a cost of $55 for every unit it produces. Its total fixed costs equal $2 million. If the company manufactures 500‚000 units compute the following: a) unit cost unit cost = variable cost + fixed cost/unit sales x = $55 + $2‚000‚000/500‚000 = $59 unit cost b) markup price if the company desires a 10% return on sales unit cost/(1 – desired return on sales) $59/(1 - .10) = $65.56 c)
