It is a way of representing the magnetic force at a point in the field. The magnitude and direction of the vector represents the strength and the direction of the magnetic force acting on a charged particle in the field.

As per my knowledge,Maxwell's equations describes the relations between changing electric and magnetic fields. That means time varying electric field can be produced by time varying magnetic field and time varying magnetic field can be produced by time varying electric field.
No. A fotball field is an area of grass or other surface painted in the outline of a football field. A line segment is a straight line which has a defined beginning and end, and is continuous between those points.

He can plow his field, and get his crops.
the responsibility of a farmer ios to work in the agricultural field producing crops and the neccesities for people. It may include different crops.
He/she makes as much crops as fit in his/her field.
From the sun and whatever fertilizers the farmer has spread on his field.
when the season is right and when the soil is nice and fertilized.
They first plow their fields along the curves of a slope. Then they disturb the soil and its plant cover as little as possible. Last they the farmer plants different crops in a field each year.
the sides of the fence are parallel to the rows of crops.
Walk around the perimeter as this causes less damage to the crops than walking straight across them.
It doesn't, at least no more than any other kind of plowing. Contour plowing is done to minimize erosion. It has nothing to do with "preparing the crops."
Not quite. Sod crops are grass crops grown for their root mass and/or their landscaping appeal. Cover crops are grasses and broadleaves, some of which are legumes, grown for their various abilities to shield soil from erosion, add organic matter to soil, build soil tilth, and add soil nitrogen. Sod crops are usually removed from the field, while cover crops are either tilled into the soil or left on top to decompose.
It is a field with no crops that is empty of all life.
Plenty ! A farmer needs to calculate how much seed he will need to cover a field. How much yield he will get from harvesting his crops. Which cows are producing the most milk. How much money he's getting paid for his produce. How much to pay his staff... the list goes on !
