Magnetic Fields
This lesson covers the concept of magnetic fields, including types of magnets such as bar magnets. It explains the flow of magnetic forces from the North pole to the South pole and the principles of attraction and repulsion between magnets. The lesson also touches on how to create a magnet and the c

Separation Techniques for Mixtures
The lesson covers various methods of separating mixtures, including filtration, evaporation, decantation, and chromatography. Each technique is explained along with its applications in obtaining pure substances from mixtures.
- 07:55 “From the word magnet, sometimes it's a magnetic, why some other substances are non-magnetic. This is usually used for separating those that are a mixture that has at least one component to be magnetic. Whereby just intro...”
- 08:41 “So magnetism sometimes can be separated from non-magnetic substances by bringing a magnet close to the mixture. Then the application is to remove magnetic impurities from thin ore and to remove all the and now the applic...”
