| + | ===Learning objectives=== |
| + | #Recall the the properties of magnets |
| + | #Relation between magnet and electricity |
| + | #How emf induced |
| + | #Emf depends upon the number of turns and speed of the magnet |
| + | #Michel faraday experiment |

| + | ===Notes for teachers=== |
| + | |
| + | ===Activities=== |
| + | #Activity 1 - Give the magnets to students and check the properties of magnets. Ask the students properties of magnets. Ask magnetic lines of force using phet tool of magnets and electromagnet. |
| + | #Activity 2 - show the different copper coils and electromagnet experiment to students and ask is it possible get electricity from magnet |
| + | #Activity 3 - Show the electromagnetic induction using galvanometer and copper coil. Observe the changes of galvanometer deflections. |
| + | #Activity 4 - Show the short video of number of coils increasing emf is increasing. |
| + | #Activity 5 - Show the video of Michel Faraday experiment. |
