Quarter 1 – Module 2

Lesson 4: Separating Mixtures Using Magnet

The module is about:

 Describing techniques in separating mixtures using a magnet.

​

After going through this module, you are expected to be able to

 describe techniques in separating mixtures by using a magnet;  apply the technique in everyday life.

What's New

​Lesson 4

Separating Mixtures Using Magnet

​ Have you experienced that your pins mixed up with your talc powder? What technique of separating the pins from the talc powder? Have you tried using a magnet in separating them? Magnetic separation one of the ways to separate mixture of metals from non-metals.

​

​

​

What's New

​

Answer the following questions:

​1. What do you usually do when a needle in your house is mixed with other nonmetal materials?

2. Have you tried using a magnet to find it?

3. How a magnet can be used to separate mixtures?

​Lesson 4

Separating Mixtures Using Magnet

​ A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.

​

​

What Is It

​

​

Components of mixtures can be separated in many ways. The method that is being used usually depends on the type of mixture. Metal and non-metal objects can be separated by using a magnet. There is no chemical reaction involved in the separation of components. Metals which are made up alloy, nickel, or cobalt are easily attracted to the magnet, while non-metals are not. Iron fillings, thumb tacks, staple wire, pins, coins, and needle are some common examples of objects that are attracted to the magnet. When they mixed with non-metals, these could be separated by magnet.

​

​

What are the objects attracted by the magnets?

​

​Magnets attract, or pull, objects made with iron. Paper clips, scissors, screws, and bolts are just a few common everyday objects that are magnetic. A magnet will not attract paper, rubber, wood, or plastic. It is not true that a magnet will attract any kind of metal.

Activity

​Direction: Say YES if separated by magnet and say NO if it is note separated by magnet.

1. acetone and water

​2. grains and husks

​3. thumb tacks and paper

​4. coins and grains

​5. staple wire and paper

​6. iron filling and sulphur powder

​7. pins and buttons

​8. soap and shampoo

​9. thumbtacks and sand

​10. push pin and rocks

Activity

​Direction: Say YES if separated by magnet and say NO if it is note separated by magnet.

1. acetone and water-NO

​2. grains and husks-NO

​3. thumb tacks and paper-YES

​4. coins and grains-YES

​5. staple wire and paper-YES

​6. iron filling and sulphur powder-YES

​7. pins and buttons-YES

​8. soap and shampoo-NO

​9. thumbtacks and sand-YES

​10. push pin and rocks-YES

What I Have Learned

Components of mixtures can be separated in many ways. The method that is being used usually depends on the type of mixture. Metal and non-metal objects can be separated by using a magnet.

​Magnets attract, or pull, objects made with iron. Paper clips, scissors, screws, and bolts are just a few common everyday objects that are magnetic. A magnet will not attract paper, rubber, wood, or plastic.

​

​Magnetic separation is important in our daily life. It can be used in electromagnetic cranes that separate magnetic material from scraps and unwanted substances. It keeps all materials pure. Recycling centres use magnetic separation often to separate components from recycling and isolate metals.
