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. − − =Assessment Activities for CCE= − ===Formative Assesment Questions=== − 1.If a magnetic needle put north and south pole, what is the direction of the a b c and d in the figure. mark 2 − *Direction of a ________ <br> − *Direction of b _______ <br> − *Direction of c _________ <br> − *Direction of d _________ <br> − − 2.The device that detects the induced emf is called _________________ mark 1 − − 3.Which the following emf is produced?
