1. True
2. False
3. Wood, plastic, glass, rubber, paper, aluminum, copper.
4. Iron, nickel, cobalt, and some rare earth metals like neodymium.
5. The strength of the magnet, the distance from the object, the material of the object, and the size/shape of the magnet.
6. North pole and South pole.
7. Each half becomes a new magnet with its own north and south pole.
8. Through its magnetic field, which exerts a force on magnetic materials without direct contact.
9. True
10. Near the geographic North and South Poles, but not exactly at them; they are located in northern Canada and near Antarctica.
11. Because the Earth’s magnetic field aligns the needle so that its north-seeking pole points toward the Earth’s magnetic north pole.
12. Electromagnetism.
13. Because they can be turned on and off, their strength can be controlled, and they are useful in devices like motors, generators, MRI machines, and cranes.
14. Magnetism is a force created by moving electric charges that causes certain materials to attract or repel each other, especially iron and similar metals, and it acts through invisible fields around magnets.
