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 is the difference between net revenue and cost of goods sold, or COGS, divided by revenue, expressed as a percentage.Generally, it is calculated as the selling price of an item, less the cost of goods sold (production or acquisition costs, essentially).ross Margin (%) = (Revenue â Cost of goods sold) / Revenue. It can be expressed in absolute terms: Gross margin = net sales â cost of goods sold + annual sales return. or as the ratio of gross profit to revenue, usually in the form of a percentage:
