Abstract

Most of the people recall their interest in science during their student days where they would collect iron present in the sand using a horseshoe magnet and observe peculiar patterns called lines of magnetic force. However, they lose their way while trying to understand magnetism. They were taught that there are N and S poles at the ends of a magnet. When cut into two pieces, once again N and S poles appear on the ends of each of the pieces. Even if the process of cutting the magnet continues, we still obtain N and S poles at the ends of each piece. In order to understand this, several questions of fundamental nature arise in the minds of clever students: To begin with, what are N and S poles? Are there only N or S poles? What are the lines of magnetic force? The general response from many teachers to these questions would be that the magnet is a material without any deep understanding. With such an off-handed argument, such students understand that science is a subject of categorization and its concepts, required to be memorized in order to obtain good grades. With such a belief, they begin to dislike science, and find that it is difficult to understand concepts this way.
