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.
In short, currents help to create magnetic fields. A moving or changing magnetic field does produce a current in a current loop or a voltage across the ends of a current loop. This is called electromagnetic induction and the current or voltage is called an induced current or an induced voltage. Electrical Induction.n short, currents help to create magnetic fields.
