Generated Voltage from Changing B. The induced emf (generated voltage) can be calculated from Faraday's Law. According to Lenz's Law the induced current in the coil produces a magnetic field to oppose the change in magnetic field which produced it.Observing the direction of the.enerated Voltage from Changing B.

The difference between net price and gross price is that gross  price refers to the total cost while net price refers to the cost  after deducting expenses. Expenses can be â¦operating costs and such. Answered.
Gross Margin. Gross margin represents the percentage of net sales that the firm takes in as gross profit. It equals gross profit divided by net sales. If you have sold $500,000 worth of product, and the cost of goods sold is $300,000, the gross profit is $200,000. The gross margin is $200,000 divided by $500,000 which equals 40 percent. A business should not focus on gross margin exclusively, since you can increase gross margin but end up with less in gross profits. If your gross profits drop to $170,000 and sales decline to $400,000, gross margin would be higher, at 42.5 percent, yet gross profits would be $30,000 lower. Contribution Margin Contribution margin is a more relevant measure to assess the profitability of additional products sold, and only takes into account variable costs.
