“Physics is so abstract that structure brings it all together” Faraday’s law is particularly challenging for pupils, according to (Chabay & Sherwood, 2006) additionally, the integral form involves the concept of flux, which is typically presented at the beginning of the course in relation to Gauss’s law and isn’t brought up again until Faraday's law is discussed. The Philippines has a low score in Science and Mathematics (the 70s), according to Paris (2019). Because of how complex physics is and the phrases and formulae that are utilized, most students believe that it is the most difficult subject to study because of this, their grades may suffer. Michael Faraday's developed simple electromagnetic generators were discovered in the years 1831-1832, which is taught to students in higher secondary schools. Faraday's law states that given a closed circuit, the induced electromotive force is equal to the rate of change of the magnetic flux encircling the circuits. The outcome of this research is designed to simplify the idea that students, when exploring the physics behind the dynamo, will have a clearer understanding of the science behind the dynamo and how it works. Through this research, it may also inspire learners to be aware of electromagnetic induction. This benefits both students and teachers since it improves their educational experiences. In general, it is important to comprehend the characteristics and effects of electromagnetic induction. The study was evaluated in character because it depended on evaluation criteria and effectiveness standards, as well as the resources at hand and the necessary level of accuracy.

Excerpt from the Book
1. Introduction
Electromagnetic induction (EMI) is an important part of physics instruction at many different levels. Students learn simple electromagnetic induction phenomena at higher secondary education, and gradually integrate more complex models into these simple ideas throughout their education. It was discovered by Michael Faraday in the early 19th century, and it was mathematically defined as Faraday's law of induction by James Clerk Maxwell. (Feynman et al., 1964) claimed that the framework of Maxwell’s theory, electromagnetic induction is a phenomenon associated with two different facts, the time variation of a magnetic field, and the movement of a conductor in a magnetic field, or a combination of the two. Britannica (2023) stated that according to Faraday ’s law, for a closed circuit, the induced electromotive force is equal to the rate of change of the magnetic flux enclosed by the circuit. With Faraday’s Law a lot have manage to create several practical applications like in generators, electric fans, etc.
In particular, (Chabay & Sherwood, 2006) state that “Faraday’s law is usually difficult for students. Moreover, the integral form involves the concept of flux, traditionally introduced at the start of the course in the context of Gauss’s law and not mentioned again until Faraday’s law is introduced”. Faraday’s law has not only been a source of discussion in the physics community but research into teaching physics provides evidence that teaching and learning can be problematic. As Paris (2019), the Philippines ranks low (70s) in Science and Mathematics. The majority of the students thinks that it is the most difficult subject to learn especially Physics due to how abstract physics is and in addition with their terms and formulas used, given this issue, their grades might be affected.
