Electricity and magnetism in physics are constantly taught to and
learned by students as a part of the academic curriculum. And it might as well
be some of the most difficult lessons instilled in the subject area. Different
areas of the topics have been regarded to have various facets, which gives us
an insight to how some concepts in the two topics are connected and/or
interrelated. These facets are: force; energy and work; and electric charge or
current. In this research, the significance and the parts of these two major
topics in physics is being discussed and expound as it seeps into the
knowledge of physics teachers of our modern curriculum.
In order to know how the facets appear in the basic knowledge of electric
and magnetic fields, the study obtained: 1) representational tools for the
students to represent the multifaceted aspects of their knowledge, and 2)
methods of analysis to discern the nature of the facets. The sample in the
research consist of third year preservice teachers who had undergone several
tests and methods to answer the question inculcated in the study. The
research was done through qualitative analysis, with the method of the
epistemic justification. This method seeks to know and uncover the four
epistemis aspects of knowledge which is; 1) ontology, 2) facts, 3) methodology
and 4) valid justification. Another method is the analysis of the relationships
between the nodes and the three facets, which will relatively aid the emergence
