read about magnetism in nature. if anything you read helps you answer the guiding question, record it as an observation.
1 according to the text, what makes lodestone a permanent magnet?
lodestone is formed during volcanic eruptions
lodestone is long-lasting and difficult to remove
lodestone continuously produces its own magnetic field
lodestone only produces a magnetic field when it is near steel
2 because they are natural magnets, every lodestone has two poles. depending on their arrangement, lodestones can attract or repel
about 2,600 years ago, farmers in the greek city of magnesia noticed strange stones in their fields. although gray and dull, these stones did something incredible: they moved! the rocks were pulled towards the farmers iron tools by an invisible force. to some, this was evidence of the stones soul. to others, the rocks remained a mystery.
centuries later, similar stones were discovered in china. scholars named them tzuh-shih, or \loving stones,\ because of the way they \hugged\ iron. in english, these remarkable rocks are called lodestones.
lodestones, like the one pictured here, are permanent magnets. this means that they continuously produce their own magnetic fields. other permanent magnets include compass needles and refrigerator magnets, although these are not found in nature.
permanent magnets can temporarily magnetize other materials. consider steel, a metal used to build skyscrapers, refrigerators, and washing machines. steel is not a permanent magnet. one steel washing machine will not be pulled towards another because neither one produces a magnetic field on its own.
however, a steel washing machine can become magnetic when its exposed to a permanent magnets field. the washing machine will lose its magnetism when the field is removed.
for example, a lodestones magnetic field will temporarily magnetize the steel washing machine. while the lodestone is nearby, the washing machine produces a magnetic field, too. when the two fields interact, bam! youve got a lodestone, paperclips, safety pins, screwdrivers, and forks stuck to your washing machine.
while pulling a lodestone off a washing machine might be a bit challenging, it certainly does highlight why humans have been drawn to magnets for millennia.
