Thus magnetic philosophy no longer furthered the interests which had maintained it, and it was abandoned. An effluvial explanation of magnetism introduced great complexity to the North-seeking behaviour of compass needles, and undermined the already troubled longitude programme. This contradiction of a distinct, yet mechanical magnetic philosophy came to a head in 1684 in an argument between Robert Hooke and Martin Lister. Magnetic philosophy lost its coherence and became subsumed in the study of effluvia. philosophers, while claiming descent from their compatriot, worked successfully to disprove this, following an experimental regime of Henry Power. An implicit condition of William Gilbert's ‘magnetic philosophy’ was the existence of a unique, immaterial magnetic virtue. The magnet served three interests of Restoration mechanical philosophers: it provided a model of cosmic forces, it suggested a solution to the problem of longitude determination, and evidence of its corpuscular mechanism would silence critics.
Due to his ignorance of astronomy in measuring the Qibla direction and ignorance of the magnitude of the Qibla direction angle in the Cirebon City area, resulting in the Qibla direction of the supermarket in the Cirebon City area experiencing a wrong Qibla direction. This method’s method is partly an error in determining the Qibla direction. Of course, using the Qibla direction application on a smartphone is an inaccurate method.
The method of measuring the Qibla direction was carried out by the musala supermarket, where the author’s research uses the Qibla compass and the Qibla direction application on the smartphone. The results of this study: that the Qibla direction of the supermarket in Cirebon City has all measured the Qibla direction. They were then analyzed by the descriptive analysis method in narration. This study aims to answer the questions that become the formulation of the problem “How is the method of measuring the Qibla direction of the supermarket prayer room in Cirebon City” and “How to analyze the accuracy of the supermarket prayer room Qibla direction in Cirebon City.” This study uses qualitative research the data collected uses observation, interviews, documentation, and literature study.
