Magnets and magnetic domains

This material is for students to use for learning about magnets and magnetic domains

The task is to learn and to answer multiple choice questions about agnets and magnetic domains using video material.

When using this material the students should wach the video and then answer to the  multiple choice questions.

The questions:

1.Why some things are permanent magnets?

• moving charge
• moving electrons
• due to the force of gravity

2. What is moving in an atom for it to have magnetism?

• electrons
• protons
• neutrons

3. Which is the most magnetic material?

• nickel
• cobalt
• iron

4. What is Magnetic domains?

• a part of the magnet
• a part of the magnet that has no charge
• a part of the magnet that has charge

5 .For a megnet to be magnetic the magnetic domains N side should be 

• Next to an other domains S side
• Next to an other domains the N side
• It does not matter 

6. When can a magnetic domain change the whey it is oriented?

• When put into a magnetic field
• You can not
• It can change due to the force of gravity

7. You can damage a magnet by?

• heating and washing it
• heating and impact (beating) it
• using it too much

8. Can a magnet change an unmagnetic pease of metal for it to be magnetic?

• Yes if the an unmagnetic metal is old
• No
• Yes if the an unmagnetic metal is in his magnetic field

9. Can everything be magnetic?

• Yes due to the force of gravity
• No
• Yes if it is old

10. Can you get two magnets out of one?

• Yes if you break it in have but you have to do it carefully
• No
• Yes if the magnet is old 

You can get maximum of 10 points 1 point for each question. 

The answers:

1. The most adequate answer is moving electrons 
2. The correct answer is electrons 
3. The correct answer is iron
4. The most adequate answer is a part of the magnet that has charge
5. The correct answer is next to an other domains S side
6. The correct answer is when put into a magnetic field
7. The most adequate answer is heating and impact (beating) it
8. The correct answer is yes if the an unmagnetic metal is in his magnetic field
9. The correct answer is no
10. The correct answer is yes if you break it in have but you have to do it carefully

You have finished the task and if you got:

10-9 points you have understood the theme and done your task very well

8-5 points you have understood the theme and done your task 

4-0 points you do not understand have magnets and magnetic domains works and you shaul watch the vidio again
