MAGNET 01 IPA

Magnet adalah yang mampu menarik benda-benda sekitar . Setiap magnet memiliki sifat kemagnetan Kemagnetan adalah kemampuan benda untuk menarik benda-benda lain disekitarnya. P engertian Magnet

C ara membuat magnet

Besi atau baja digosokkan searah dengan magnet maka akan menjadi magnet atau memiliki sifat kemagnetan. Setiap kali selesai satu gosokan magnet harus diangkat sedikit menjauh dari bahan yang digunakan untuk membuat magnet. Nantinya, jika menggosok dengan kutub utara magnet maka ya n g digosok akan menjadi kutub utara juga. G osokan

Besi atau baja didekatkan dengan magnet maka akan menjadi magnet atau memiliki sifat kemagnetan. Sifat kemagnetan yang dihasilkan hanya sementara. Jika magnet dijauhkan maka besi akan kehilangan sifat kemagnetannya. — Induksi

Membuat magnet dengan dialiri listrik dilakukan dengan cara melilitkan kabel ke benda magnetis yang akan dibuat magnet, misalnya besi. Kedua ujung kabel dihubungkan dengan baterai atau sumber listrik yang lain. Jika sumber listrik dilepas, sifat kemagnetan pada electromagnet juga akan hilang. Jadi magnet yang dihasilkan bersifat sementara. E lektromagnet

Video Pembuatan Magnet

Penggunaan Magnet Pada microfon terdapat magnet sehingga mengubah energi suara menjadi energi listrik Pintu lemari es telah dipasangi magnet sehingga dapat tertutup rapat Dinamo sepeda untuk menghasilkan medan elektromagnetik yang akan menjadi energi listrik Kompas sebagai penunjuk arah utara-selatan

Lambang Pancasila

Berdoa dan bersyukur kepada Tuhan sebelum memulai aktivitas harian Tidak memilih-milih teman berdasarkan agama atau keyakinan Pengamalan Sila Pertama Pancasila Saling menghormati antar sesama manusia walau memiliki keyakinan yang berbeda. Selalu menghargai dan tidak menggagu hari besar atau ibadah setiap agama yang ada di Indonesia.

Bersyukur adalah berterima kasih dengan semua yang diberikan Tuhan . Sikap selalu bersyukur adalah salah satu contoh pengamalan sila pertama pancasila

Cara Mensyukuri Keberagaman Makhluk Hidup Menjaga kesehatan tubuh Merawat tanaman dan hewan Menjaga kelesatarian alam Memuji dan menghargai orang lain Menjaga kesehatan tubuh

Contoh Pengamalan Sila ke 1

Nickel Iron Cobalt Three ferromagnetic materials Mercury is the closest planet to the Sun and the smallest in the entire Solar System Venus has a beautiful name and is the second planet from the Sun. It’s terribly hot Despite being red, Mars is actually a very cold place. It’s full of iron oxide dust

Composition of a magnet S N South pole North pole Neutral line Higher traction zone Higher traction zone Lower attraction Interaction Attraction Two types of force Repulsion If the poles are opposite, they attract each other If poles are the same, they repel each other
