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 gross price would be the price before deductions. The net price is after deductions.
Again, gross margin is just the direct percentage of profit in the sale price. In accounting, the gross margin refers to sales minus cost of goods sold. It is not necessarily profit as other expenses such as sales, administrative, and financial must be deducted.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:
