Description | ||
| The magnetic field around a permanent magnet, like the gravitational field around a massive object, is not only invisible, but hard for students to comprehend. With no concrete experience to draw from, they tend to ignore this basic concept, or at best, memorize facts about it. This activity shows how to map a magnetic field, and to find how a bar magnet's field combines with the Earth's magnetic field to form a complex resultant field | ||
