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%.
Gross profit definition. Gross profit is the revenue left over after you deduct the costs of making a product or providing a service. You can find the gross profit by subtracting the cost of goods sold (COGS) from the revenue. For example, if a company had $10,000 in revenue and $4,000 in COGS, the gross profit would be $6,000. This figure is on your income statement. To calculate gross profit, use this formula: Revenue â Cost of Goods Sold (COGS) To find the gross profit, you need to understand what revenue and cost of goods sold are. Revenue is equal to the total amount you make in sales.
