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.
1 A poloidal magnetic field is generated by a current flowing in a ring, and is found, for example, in a tokamak. 2  A radial magnetic field is one in which field lines are directed from the center outwards, similar to the spokes in a bicycle wheel. 3  An example can be found in a loudspeaker transducers (driver).he force on a current carrying wire is similar to that of a moving charge as expected since a charge carrying wire is a collection of moving charges. A current-carrying wire feels a force in the presence of a magnetic field.
