Magnet and Electricity Trivia By Sophie, Kate Lucia, and Vanathi

Scoring :) 1. Please keep score of how many questions you get right. Answers after each question 2. If you get 0-13 questions right, but miss the rest, we give you a 1(you need to study more) 3. If you get questions right, we give you a 2 (study a little more) 4. If you get questions right, which you probably will, we give you a 3 5. If you get them all right, Great Job, you got a 4!( You don't need to study, but study more anyway)

Question 1 How are magnetic fields created?

Answer 1 Magnetic fields are created by electric currents and by putting opposite poles on two magnets together.

Question 2 Order the rarity of materials that attract to magnets from least to greatest.

Answer 2 Iron, Nickel, Cobalt, Neodymium and Ceramic.

Question 3 Choose 2 things that temporary magnets can be.

Answer 3 Telephones, pins, electric motors, iron or steel nails and paper clips.

Question 4 Which two poles of a magnet have to be near each other to attract?

Answer 4 North and South.

Question 5 Why do magnets attract?

Answer 5 Because the atoms are all lined up and the magnetic field’s force pulled them together.

Question 6 How are electronics destroyed by magnets?

Answer 6 The magnet tries to line the atoms up in the electronic(s) with the magnet, which makes the atoms in the electronic not function the way it should.

Question 7 Name an object with magnets in it.

Answer 7 Razor, refrigerator magnet, and any type of thing with a motor.

Question 8 What type of magnet is this?

Answer 8 Horseshoe magnet.

Question 9 Is there an east or west pole on a magnet?Why? S ? ? N

Answer 9 There are no East and West poles on a magnet because a magnet only repels and attracts, disabling the magnet to have more than 2 things to do.

Question 10 What is the build-up or release of electric charges called?

Answer 10 Static Electricity.

Question 11 What kind of energy is lightning?

Answer 11 Static Electricity.

Question 12 If a material loses electrons, then it has a ________ charge.

Answer 12 It has a positive charge.

Question 13 If a material gains electrons it has a ________ charge

Answer 13 It has a negative charge.

Question 14 Which doesn’t fit: ceramic, aluminum, hammer, nails, neodymium?Why?

Answer 14 Aluminum doesn’t fit because it is not magnetic.

Question 15 What is the AlNiCo magnet made from?

Answer 15 Aluminum,Nickel and Cobalt.

Question 16 What is the atomic number of nickel?

Question 16 28

Question 17 In what are electromagnets used?

Answer 17 They are used for electric motors, loudspeakers, etc.

Question 18 What color is cobalt?

Answer 18 Light blue when mixed with glass and silver when by itself.

Question 19 A complete path for moving electrons to go is called a _______.

Answer 19 A circuit.

Question 20 Electric currents can’t flow in this circuit. True or False?

Answer 20 True, this is an open circuit.

Question 21 What side on a magnet attracts North?

Answer 21 The South pole and vice-versa

Question 22 If one bulb goes out (burns) in a series circuit, what happens to the rest of the bulbs? >

Answer 22 The other bulbs will all go out.

Question 23 Name at least 3 types of magnets. If you can name 2 more, good job!

Answer 23 Iron, Nickel, Cobalt, Ceramic, Neodymium, horseshoe magnet, disk magnet, bar magnet, electromagnet, permanent magnet, temporary magnets, ring magnet, etc.

Question 24 What are 3 ways to demagnetize a magnet?

Answer 24 heat throwing down to the floor many times keeping North and North (vice versa) together for a long time

GOOD JOB:) :) :) You should pass the Science Test!!!
