SSC MCQ Question Ans MAGNETIC EFFECT OF CURRENT. As the current has a magnetic effect, the magnet has the electric effect also. Many electric tools have been made by using these two effects. These tools have solved many problems of us, have brought out various comforts and have developed the standard of our life. In this chapter, we shall discuss the functions and uses of the electromagnet, electromagnetic induction, induced the current and induced electric power, electric motor, generator, transformer, etc.
SSC MCQ Question Ans MAGNETIC EFFECT OF CURRENT
We can increase the magnetic field intensity by coiling the above-mentioned wire. Due to the flow of the current through the coil, most of the lines of the force will be concentrated in the center of the coil. The magnetic field will be look alike the magnetic field of the bar magnet. This type of coil is called Solenoid. If we insert an iron rod through it, the iron rod will be turned into the magnet. If we stop the current, it will not remain magnet. If the direction of the current is changed, the pole of the magnet will be changed. Through this process, the iron is turned into the magnet which is called electromagnet.
