Transcript of Magnetism in the 21st Century

Magnets have been used to treat depressionand also Parkinsons disease, and migraines
It is believed that the electromagnetic field sends signals to nerve endings that can rejuvenate and encourage action The biggest stars make the biggest magnets. When the star dies, a magnetar forms from the collasped core of the star.
A typical magnetar possess a magnetic field one quadrillion times (1,000,000,000,000,000) times stornger than the Earth's magnetic field.
If a magnetar were put halfway to the moon, it could wipe away all data from every credit card on Earth!!!!!!
A magnet at the heart of products like cell phones and hybrid cars relies on an increasing scarce supply of a rare Earth element called neodymium.
The neodymium-iron-boron magnet is the most powerful commercial magnet available today. It also plays an important role in many technologies crucial to the U.S economy and defense. Maglev,or magnetic levitation is a system of transportation, that suspends, guides and propels vechicles mainly trains.
It uses magnetic leviation from very large magnets for life and propulsion.This method is said to be faster than the wheeled transit systems.
Small magnetic toys are a hazard to children.
If a child swallows two magnetic parts at different times then the magnest can attract to each other inside the body and cause serious injury, infection, or even death.
The magnets can only be removed with surgery Resources
