1. Learning Objectives: What are force fields? Describe field patterns of: - Bar magnets - Straight wires - Plane coils - Solenoids

2. What are Force Fields? There must be some sort of force field around the black box that attracts the magnet When the box is cold it is attracted by the magnet, but when it is warm it is not attracted Everybody knows that force fields are Science Fiction and that only Superheroes can create them!

6. Follow the instructions your teacher will give you and draw the pattern observed in these three situations. Bar magnets field patterns N S N S N S N S S N Show field

7. Some magnetic fields are naturally occurring, like in Magnetite, others can be induced by a current. Wires, coils and solenoids Courtesy of Rob LavinskyRob Lavinsky

8. Wires, coils and solenoids

9. Magnetic fields are a type of force field The field patterns of: Bar Magnets Wires Plain Coils Solenoids Learning outcomes

10. Your task is to draw a mind map with “Magnetic Fields” as the central topic. Use the following rules: -Use many colours for branches and text -Use one word only on each branch -Use as many images as possible -Link different concepts together with arrows to help you give meaning to and create connections in your work Watch the video in the next slide to see some guidelines on effective mind mapping Homework
