Jeopardy Magnetic Earth Magnetic Fields More Magetic Earth Magnets Mystery Question What is the name of the region of Earths magnetic field that is shaped by the solar wind? 100 Category 1 One part of a freely spinning magnet always points to : A. magnetic field B. Earths magnetic pole in the Northern Hemisphere C. the center of the Earth D. the East 200 Category 1 TRUE or FALSE? The Earthss magnetic poles are the part where the magnetic effect is the weakest. 300 Category 1 What are the glowing regions on the Earths poles that are caused by particles from the Sun? 400 Category 1 Are magnetic forces: A. Contact Forces B. Field Forces C. Explain your answer. 100 Category 2 Describe how the force between a Magnet and an iron object changes as the objects move closer to each other. 200 Category 2 TRUE or FALSE? Magnetic poles that are the same attract each other. 300 Category 2 Look at the Magnetic Field lines below: Explain what is happening using scientific terms. 400 Category 2 Both the Earth and Sun have flipped their magnetic poles. How often does the Suns magnetic pole usually flip? 100 Category 3 Earth is like a bar magnet because it has 1. ____________________ 2. ____________________ 3.____________________ 200 Category 3 TRUE or FALSE? Charged particles from the solar wind come closest to Earth at the Equator, where Earths magnetic field lines dip down to Earths surface. 300 Category 3 What do spinning electrons produce in a magnet? 400 Category 3 2 magnets move closer to each other, just like the picture below. Describe the force they exert on each other. 100 Category 4 Describe how you could make a temporary magnet (think about our labs last week). 200 Category 4 Using evidence from the picture below, give a scientific explanation (make a claim) that describes the differences between the magnetic energy in each example: 300 Category 4 Describe the difference between an non- magnetized piece of iron and a magnetized piece of iron. 400 Category 4 __________ is the interaction (push or pull) between 2 or more objects. 100 Category 5 The region around a magnetized object where the objects magnetic force is exerted on other objects is called _________ ________. 200 Category 5 300 How often does the Earths magnetic field flip? Category 5 Opposites ______________ ! 400 Category 5 MAGNETOSPHERE 100 Category 1 Answer B. Earths magnetic pole in the Northern Hemisphere 200 Category 1 Answer FALSE. The North and South Poles have the strongest magnetic effect. 300 Category 1 Answer The Auroras ( North- Aurora Borealis, South-Aurora Australius) 400 Category 1 Answer B. Field Forces 100 Category 2 Answer As 2 objects move closer to each other, the force between objects increases. 200 Category 2 Answer FALSE. Like charges REPEL. 300 Category 2 Answer The magnetic poles facing each other are the same, so the poles are repelling each other (or: there are repulsive forces between the poles). 400 Category 2 Answer Every 11 years. 100 Category 3 Answer 1. Has a north and south pole 2. Has a magnetic field 3. Has a magnetic force 200 Category 3 Answer FALSE. The solar winds come closest to the North and South Pole. 300 Category 3 Answer Magnetic Field 400 Category 3 Answer Attraction 100 Category 4 Answer You could take a sewing needle and rub it times on a small magnet. The needle will be only magnetized for a short time (temporarily). 200 Category 4 Answer Image A has attractive forces and image B and C have repulsive forces. Sample Evidence: In image A, the lines are connecting between the two magnets. The lines connect with the north and south pole when the opposite poles are closer together. In image B and C, the lines are not connecting between the two magnets. 300 Category 4 Answer A non-magnetized piece of iron has its Electrons moving randomly (in all directions) A magnetized piece of iron has its Electrons moving in the same direction. 400 Category 4 answer Force 100 Category 5 Answer Magnetic Field 200 Category 5 Answer The Earths magnetic field flips every million years. 300 Category 5 Answer Attract!!
