Which of these determines whether or not a increases. Which statement explains why this material is magnetic? would happen? A. the density of the material A. The like poles of the magnets are pointed at B. the weight of the material on Earth each other and move farther apart. C. the alignment of atoms in the material B. The like poles of the magnets are pointed at each other and move closer together. D. the number of elements that make up the material C. The unlike poles of the magnets are pointed at each other and move farther apart. 4. Candice claims that all magnets have two D. The unlike poles of the magnets are pointed magnetic poles. Which of these observations at each other and move closer together. would best support her claim? A. Iron is attracted to a magnet but not to 2. Kim has two bar magnets. First, she places other pieces of iron. them beside one another, as shown in Picture A. Then, she moves one of the bar magnets B. When a bar magnet is cut in half, each half so they are placed as shown in Picture B. has a north pole and a south pole. How did the magnetic force change? C. The north pole of a compass needle is attracted to the south pole of a bar magnet. D. The strength of the magnetic force from a bar magnet decreases as the magnet is pulled away from another object. 5. Angela tries to pick up a copper penny using a bar magnet, but the penny does not move. Next, she tries to pick up an iron nail using the bar magnet, and the nail lifts up toward A. The bars go from attracting each other to the magnet. Which of the following best repelling each other. describes a ferromagnetic material like iron? B. The bars go from repelling each other to A. Ferromagnetic materials do not conduct attracting each other. electricity. C. The bars go from repelling each other to B. Ferromagnetic materials always produce a the second bar rotating. magnetic force. D. The bars go from attracting each other to C. Ferromagnetic materials are nonmetals that the second bar rotating. produce magnetic forces. D. Ferromagnetic materials have magnetic domains that align with a magnetic field.

Why can some objects be magnetized by new illusion for her show. She plans to hide rubbing one pole of an existing magnet in strong magnets in her shoes and inside a one direction along the object? special rug on the stage. When she tests the A.

What will happen if she flips the poles the object. of the magnets in each of her shoes? B. The motion of the existing magnet against A. Her shoes will float above the rug. the object scrambles, or unaligns, the B. Her shoes will still be stuck to the rug. magnetic domains of the object. C. Her shoes will no longer be affected by C. The motion of the existing magnet against the rug. the object generates an electric current that transforms the object into an D. Her shoes will stick to each other instead of electromagnet. to the rug. D. The motion of the existing magnet against the object wears away the object’s surface, exposing the naturally occurring magnets underneath. Read each statement. Write your answer on the lines. 8. A student finds three unmarked bar magnets in a lab. She wants to know how strong each of the magnets is. She also has a set of paper clips. Explain how she could use the paper clips to determine the strength of each magnet.

First, he moves the magnet toward the middle of the copper rod. Next, he moves the magnet toward the middle of the iron rod. Finally, he moves the magnet toward the middle of the steel rod. In each step of his investigation, he writes down his observations. Describe the goal of Ajit’s investigation. Identify one way Ajit can improve his investigation. 10. Use the diagram to answer the question. The image models the alignment of magnetic domains in a material. Explain how a model of the material would look if it became magnetized. Explain why the domains in your model would produce a magnetic material while the domains in the first model do not.
