Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.

Question: "Name two benefits of Earths magnetic field."

Response: "Assists animals with travel and direction"

"Femme" is an apt description of the depiction of Madame White Snake and all her incarnations. It refers to a woman who is dangerously attractive, and lures men to their downfall with her sexual attractiveness. In both incarnations of Madame White snake, the authors depict her as bewitchingly beautiful. Toyoo, her human lover in "Lust of the White Serpant" cannot shake the image of her beauty from his mind and dreams of her, and finds himself "disturbed and agitated" by her "ethereal beauty". In "Eternal Prisoner," Madame White Snake's bewitching beauty follows her lover Hsu into his dreams, and the next morning "he was so distracted that he could not concentrate on doing business." Both of these stories align negative connotations with her beauty, suggesting that her sexuality is the cause of their distraction. In addition to distracting sexuality, the irregular characterization of Madame White Snake might be another trait her character has in common with the archetypical noir femme fatale. In her essay analyzing the noir film from a feminist perspective, Christine Gledhill writes "Not only is the hero frequently not sure whether the woman is honest or a deceiver, but the heroine's characterisation is itself fractured so that it is not evident to the audience whether she fills the [femme fatale] stereotype or not".

Question: "What are the names of Madame White's Snake lovers."

Response: "Monsieur Tuyo"

- no

Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it.

Question: "What are a few examples of non-contact force?"

Response: "Contact force"

- no
