Question

describing magnets
with the help of science books and your previous lessons on magnetism, fill in the blanks with the correct answers. choose from the word list below.
poles attracts north pole
magnetic field south pole iron filings
magnetism temporary magnet bar magnet
solenoid magnetic induction permanent magnet
1.________ is commonly attributed to ferromagnetism and electromagnetism depending on the material and moving charges. stroking with a 2.______ is one of the ways to induce or cause magnetism in an object that can be magnetized. attraction happens after 3.______ occurs. a magnet 4.________, but do not repel, unmagnetized ferromagnetic materials such as iron, nickel, cobalt and some of its alloys like steel and alnico.
a 5.________ surrounds a magnet. the magnetic field is strongest at the 6.______ where the magnetic lines of induction (flux) are closest. the magnetic field pattern can be shown using 7. iron filings that align along magnetic lines of induction. the magnetic lines of induction leave the 8.______ and enter the 9.______ in close loops and can be indicated by the north pole of a compass. the earth acts like a giant 10.________ and has a magnetic field similar to it.

Explanation:

1. Magnetism is a general term encompassing ferromagnetism and electromagnetism.
2. A permanent magnet can be used to stroke an object to induce magnetism.
3. Magnetic induction is the process that leads to attraction.
4. A magnet attracts unmagnetized ferromagnetic materials.
5. A magnetic field surrounds a magnet.
6. The poles (north and south) are where the magnetic field is strongest.
7. (Already filled as iron filings)
8. Magnetic lines of induction leave the north pole.
9. And enter the south pole.
10. The Earth acts like a giant bar magnet.
