Integrated Management. To eliminate cogongrass and prevent regrowth, the rhizomes must be destroyed. It has been shown that an integrated approach that combines burning, tillage (mechanical disturbance), and chemical applications provide the best solution for cogongrass management.
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off.Electromagnets usually consist of a large number of closely spaced turns of wire that create the magnetic field.he magnetic field of electromagnets in the general case is given by Ampere's Law : which says that the integral of the magnetizing field H around any closed loop of the field is equal to the sum of the current flowing through the loop.
geomagnetic field. The magnetic field of the earth which drifts over time. It is created by electrical forces that are formed by the movement of the molten metals in the outer core. Is different from the magnetic field of a bar magnet.n space the area that surrounds the Earth & contains Earth's geomagnetic field The area surrounding Earth that contains Earth's magnetic field & is created by the interaction of Earth's magnetic field with gases from the Sun. It also keeps Earth from receiving too much energy from the Sun. î î î.
