Questions and Answers
  • 1. 

    Benda yang dapat di tarik kuat oleh magnet disebut……..

    • A.

      Diamagnetik

    • B.

      Paramagnetik

    • C.

      Feromagnetik

    • D.

      Non magnetik

    Correct Answer
    C. Feromagnetik
    Explanation
    The correct answer is "feromagnetik." Ferromagnetic materials are those that can be strongly attracted to a magnet. These materials have permanent magnetic properties and can retain their magnetization even after the external magnetic field is removed. Examples of ferromagnetic materials include iron, nickel, and cobalt.

  • 2. 

    Contoh benda yang dapat di tarik lemah oleh magnet adalah…….

    • A.

      Tembaga

    • B.

      Baja

    • C.

      Alumunium

    • D.

      Besi

    Correct Answer
    A. Tembaga
    Explanation
    Tembaga dapat ditarik lemah oleh magnet karena tembaga adalah logam yang memiliki sifat diamagnetik. Dalam sifat diamagnetik, material tidak memiliki medan magnetik internal yang signifikan sehingga tidak menunjukkan respons yang kuat terhadap medan magnet eksternal. Sebagai hasilnya, tembaga hanya sedikit tertarik oleh magnet dan dapat dengan mudah ditarik lemah oleh magnet.

    Rate this question:

  • 3. 

    Serbuk besi yang di taburkan pada sebuah magnet batang hanya akan melekat pada ujung-ujungnya saja karena…….

    • A.

      Medan magnet pada batang lemah

    • B.

      Bagian tengah magnet bersifat netral

    • C.

      Magnet pada batang memiliki dua kutub

    • D.

      Penaburan serbuk besi tidak merata

    Correct Answer
    B. Bagian tengah magnet bersifat netral
    Explanation
    The correct answer is "bagian tengah magnet bersifat netral" because the powder iron is attracted to the ends of the magnet due to the strong magnetic field concentrated at the ends. In the middle of the magnet, the magnetic field is weaker, so the iron powder does not stick to it.

    Rate this question:

  • 4. 

    Daerah di sekitar magnet yang masih terdapat pengaruh kemagnetan adalah……

    • A.

      Medan listrik

    • B.

      Medan magnet

    • C.

      Gaya magnet

    • D.

      Gaya gerak listrik

    Correct Answer
    B. Medan magnet
    Explanation
    The correct answer is "medan magnet". The region around a magnet where its magnetic influence can still be detected is called the magnetic field or "medan magnet". This field is responsible for the magnetic forces and interactions between magnets and magnetic materials.

    Rate this question:

  • 5. 

     Pernyataan tentang garis-garis gaya magnet yang benar berikut ini, kecuali…….

    • A.

      Garis-garis gaya magnet selalu keluar dari kutub selatan magnet masuk ke kutub utara magnet

    • B.

      Garis-garis gaya magnet tidak pernah saling berpotongan

    • C.

      Garis-garis gaya magnet selalu keluar dari kutub utara magnet masuk ke kutub selatan magnet

    • D.

      Tempat yang garis-garis gaya magnetnya rapat menunjukkan medan magnetnya lemah

    Correct Answer(s)
    B. Garis-garis gaya magnet tidak pernah saling berpotongan
    C. Garis-garis gaya magnet selalu keluar dari kutub utara magnet masuk ke kutub selatan magnet
    Explanation
    The correct answer is "garis-garis gaya magnet tidak pernah saling berpotongan". This statement is incorrect because magnetic field lines can intersect each other. Magnetic field lines represent the direction and strength of the magnetic field, and they can cross each other at any point. Therefore, this statement contradicts the nature of magnetic field lines.

    Rate this question:

  • 6. 

    Suatu benda padat yang dapat menarik benda lainnya disebut dengan magnet.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A solid object that can attract other objects is called a magnet.

    Rate this question:

  • 7. 

    Elektromagnet di buat dengan cara memasukkan batang besi ke dalam kumparan.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    An electromagnet is not made by inserting an iron rod into a coil. Instead, an electromagnet is created by passing an electric current through a coil of wire, which generates a magnetic field. The magnetic field is then amplified by placing a ferromagnetic material, such as an iron core, inside the coil. This process allows the electromagnet to attract and hold objects, and it is commonly used in various applications such as electric motors and magnetic locks.

  • 8. 

      Perhatikan gambar di bawah ini      Pola garis serbuk besi pada gambar di atas menunjukkan adanya……..

    Correct Answer
    garis gaya magnet
    fluks magnetik
    Explanation
    The pattern of iron filings in the image indicates the presence of magnetic field lines and magnetic flux.

    Rate this question:

  • 9. 

     Perhatikan gambar di bawah ini! Pada pembuatan magnet dengan cara penggosokan di atas, ujung A merupakan kutub……  

    Correct Answer
    Selatan
    Explanation
    Dalam pembuatan magnet dengan cara penggosokan, ujung A akan menjadi kutub selatan. Hal ini karena saat benda magnetik digosokkan ke benda non-magnetik, elektron-elektron dalam benda non-magnetik akan terpengaruh dan mengalami perubahan arah geraknya. Akibatnya, terbentuklah medan magnet yang menghasilkan kutub selatan pada ujung A.
