Have you ever wondered how compasses work or why refrigerator magnets stick? Let's dive into the fascinating world of magnets and electromagnets, exploring their properties, behaviors, and real-world applications through an interactive learning experience.
A magnetic field is an invisible area of influence that surrounds magnets and electromagnets. Think of it as an unseen hand that can push or pull on magnetic materials. Through our interactive simulation, you can actually visualize these invisible fields by moving virtual iron filings around different magnets and observing the distinct patterns they form.
Permanent magnets, like the classic bar magnet, have a north and south pole. The Earth itself acts as a giant bar magnet, with its magnetic poles playing a crucial role in navigation and protecting us from harmful solar radiation. In our simulation, you can:
Unlike permanent magnets, electromagnets can be turned on and off. They create magnetic fields using electric current flowing through a coil of wire, often wrapped around an iron core. Our interactive simulation lets you explore how:
Our interactive simulation brings these concepts to life with features designed for all learners:
