Dear 4INT students,
Please try posting a comment so that I know you have access to Padlet.

Post a comment in the following format, please!
1) Full Name
2) What have you learnt about magnets so far?
3) What are you unsure of about magnets?
4) What is one thing you found most interesting about magnets?
4) Any questions you have on the topic of magnets.

Gentle reminder to post responsibly. ]]> 2018-02-09 01:54:18 UTC https://padlet.com/msliwenlin123/4INT_1/wish/229877492 https://padlet.com/msliwenlin123/4INT_1/wish/229911127   2) I had learnt that a magnet has 2 poles, north pole and south pole, they can attract (pull) or repel (push) a magnetic object but cannot attract or repel on non magnetic material.
 3) I am unsure about the  magnetic field. What pattern will it form if iron fillings is sprinkled on a different types of magnet ?
 4) I find most interesting about magnet is when I can make a temporary magnet using the stroke method.  
5) How magnetism is used in musical instrument?]]> 2018-02-09 07:01:08 UTC https://padlet.com/msliwenlin123/4INT_1/wish/229911127 ell_chubby https://padlet.com/msliwenlin123/4INT_1/wish/229913650 1) What I Have Learnt:
Magnets can attract and repel other magnets.Magnets attract magnetic materials such as steel, iron and cobalt.Magnets cannot attract non-magnetic materials such as wood,plastic,aluminium and copper.If you put two magnets with like poles facing each other, they repel each other,if you put two magnets with unlike poles facing each other,they attract each other.If you accidentally break a magnet into half, they will become two magnets. You can make a magnetic material into a magnet by using a magnet to stroke the magnetic material.The more you stroke the magnetic material, the stronger the magnetism of the magnetic material.The north and south poles of a magnet has the strongest magnetism.When you shake a magnet and it comes to a rest, it will point at the north and south directions.

2) What I Am Unsure About Magnets:
I am unsure how magnets gain their magnetism.Why do they attract?Why do they repel?And why do they rest pointing at the north and south directions.

3) What I Find Most Interesting About Magnets:
When you can turn a magnetic material into a magnet, it is very interesting. It is also interesting when you shake a magnet and it comes to a rest, they will point to the north and south directions.]]> 2018-02-09 07:19:09 UTC https://padlet.com/msliwenlin123/4INT_1/wish/229913650 https://padlet.com/msliwenlin123/4INT_1/wish/229921875 1)Tan jia en:2)magnets can repel and attract each other and magnetic materials.They will be pointing to N-S direction when it is freely suspended in the air . U can make a temporary magnet with a iron nail using the stroking method.Iron ,cobalt, and nickel,etc.they are some of the materials that are able to get attracted to any magnet.And when a magnet drops and breaks into two then they become two permanent magnets

3) l am quite unsure of the temporary magnets.Why must they be temporary instead of permanent after using the stroking method.
4) l am astonished by how u can make a magnet ( a temporary one) using the stroking method ]]> 2018-02-09 08:02:56 UTC https://padlet.com/msliwenlin123/4INT_1/wish/229923051 https://padlet.com/msliwenlin123/4INT_1/wish/229927319 Tan jia en

2. I have learnt that
2a. Magnets attract and repel each other.
2b. Magnets attract steel, iron, cobalt and nickel
2c. Magnets CANNOT attract wood, plastic, glass and rubber. Amazingly, not all metals will be attracted. 
eg. Copper
2d. When magnets rest, they point in the north south direction.
4. I am very interested when you use different ways to make a temporary magnet.

A magnet will only rest at North and South directions and attracts magnetic materials such as steel, iron, nickel and others. It doesn't attract non magnetic materials such as wood, plastic and others.

I am uncertain why does a magnet has a magnetic field and find magnet is interesting because it is the only element has magnetic field. No other further question I would like to enquire.]]> 2018-02-09 11:11:14 UTC https://padlet.com/msliwenlin123/4INT_1/wish/229969324 pq_yun https://padlet.com/msliwenlin123/4INT_1/wish/230021220 Magnets repel and attract each other
Magnets  attract steel, iron, nickel
magnets CANNOT be attracted to cloth ,wood ,glass ,plastic rubber and others material
When they (MAGNETS) rest they will point to the north and south poles

a magnet that can be stuck on the man that you let us watch

they do not need to move and they will either attract or repel each other

how are lodestone created

I also learnt that when a magnet dropped at the floor and split into two, it formed two new magnets.

2.  Making a temporary magnet using the stroking magnet.

I also learnt magnets cannot attract non-magnetic objects such as cloth, book ,cardboard, paper and many other non-magnetic objects.

2) Does magnet only attract metals?/How does magnet gain its ability to attract metals?/Can we find natural magnetic material on Earth?/ Why is magnet strongest at its pole?/Can a magnet switch its pole?/What can I do to make the magnet lose its power?/
3) Magnets can be found naturally in form of rocks. Example, lodestones. 
4) Is there a way to measure the power of a magnet and how?

1.magnets have 2 poles.The North pole and the South pole.
2.like poles attract and unlike poles repel.
3.a magnet at rest will always rest and point at the North-South direction.
4.magnets can be found in rocks.
I think am not unsure of anything about magnets.
The thing I found most intresting about magnets is that they can attract and repel
each other.
I have a question and that is do magnectic men really exist? And will they really have a magnectic field?
