Instead of thinking about one field changing in response to the change of the other, it is more correct to say that. whenever the magnetic field is changing, so is the electric field, and vice versa.The way these fields change is governed by Maxwell's equations.This way, we do not arrive at the confusion OP has.nstead of thinking about one field changing in response to the change of the other, it is more correct to say that. whenever the magnetic field is changing, so is the electric field, and vice versa.
Gross profit = net sales â cost of goods sold. Gross profit percentage = [(net sales â cost of goods sold)/net sales] Ã 100%.
In accounting, net profit is equal to the gross profit minus overheads and interest payable for a given time period (usually, the accounting period). A common synonym for net profit when discussing financial statements (which include a balance sheet and an income statement) is the bottom line.
