Abstract

This quantitative research study was conducted to illustrate the relationship between temperature and the holding force of an electromagnet in a changing magnetic field To answer this question an electromagnet was connected to the direct current while being heated to different temperatures so as to observe at what temperature a nut attached to the electromagnet would fall off The results showed that with an increase in the electromagnet s temperature a lower attractive force is noted The results also revealed that this relation is linear The implications of this study could be used to design more energy efficient electromagnets
