In summary, magnetic fields can be controlled through the use of various techniques such as electromagnets, permanent magnets, and magnetic materials. Electromagnets can be turned on and off by controlling the flow of electric current, while permanent magnets have a fixed magnetic field that can be manipulated by changing its orientation or by using other magnets. Magnetic materials, on the other hand, can have their magnetic properties altered by applying an external magnetic field. These methods allow for the manipulation and control of magnetic fields for various applications in technology and science.
