The video tutorial explores how the number of batteries affects the strength of an electromagnet. It includes two experiments: one using a single battery and another using two batteries. The tutorial provides a step-by-step guide to building an electromagnet, lists necessary materials, and discusses the results of each experiment. Observations show that increasing the number of batteries enhances the electromagnet's strength, attracting more paper clips. The video concludes with an analysis of how to create a stronger electromagnet by adjusting the number of batteries.
