1. FIGURE 1 below shows a circular loop L1 of radius 7 cm carries a 12 A current and another one loop L2 of radius 1.6 cm, having 30 turns and carrying a 3A current is placed at the centre of loop L1. What will be the resultant magnetic field at point P if the two current flow in the opposite direction?
A circular loop L₁ with a radius of 7 cm carries a current of 12 A and another circular loop L₂ with a radius of 1.6 cm, has 30 turns and a current of 3A is placed at the center of the circle L₁. The resultant magnetic field at point P if two currents flow in opposite directions is equal to [tex]2,305\pi \times 10^{-3}~T[/tex] or [tex]7,24 \times 10^{-3}~T[/tex] with the resultant inward.
Penjelasan dengan langkah-langkah:Diketahui:
Kawat melingkar L₁ dengan radius r₁ = 7 cm dialiri arus listrik 12 A.Kawat melingkar L₂ dengan N = 30 lilitan dan radius r₂ = 1,6 cm dialiri arus listrik 3 A.Kedua kawat sepusat pada titik P.Ditanya:
Berapakah resultan medan magnet di titik P jika kedua arus mengalir dalam arah yang berlawanan?
Proses:
Rumus induksi medan magnet kawat melingkar di pusat lingkaran adalah sebagai berikut.
[tex]\boxed{B=\frac{\mu_0 I N}{2a} }[/tex]
Keterangan:
B = medan magnet (T atau Wb/m²)I = kuat arus (A)N = banyak lilitana = radius (m)[tex]\mu_0 = 4\pi \times 10^{-7}[/tex]Aturan tangan kanan pada kawat melingkar berarus.
Arah B = arah ibu jariArah I = arah putaran keempat jari tanganStep-1: hitung medan magnet L₁
[tex]\boxed{B_1=\frac{(4\pi \times 10^{-7})(12)(1)}{2(7\times 10^{-2})} }[/tex]
[tex]B_1=3,43\pi \times 10^{-3}~T[/tex] dengan vektor B₁ berarah ke dalam.
Step-2: hitung medan magnet L₂
[tex]\boxed{B_2=\frac{(4\pi \times 10^{-7})(3)(30)}{2(1,6\times 10^{-2})} }[/tex]
[tex]B_2=1,125\pi \times 10^{-3}~T[/tex] dengan vektor B₂ berarah ke luar
Step-3: hitung resultan medan magnet di titik P
Misalnya acuan arah positif adalah ke dalam, maka [tex]\Sigma B = B_1 - B_2.[/tex]
[tex]\Sigma B = 3,43\pi \times 10^{-3}- 1,125\pi \times 10^{-3}[/tex]
[tex]\therefore \Sigma B = 2,305\pi \times 10^{-3}~T[/tex] atau [tex]\Sigma B = 7,24 \times 10^{-3}~T.[/tex]
Karena hasilnya positif, maka resultan medan magnetik berarah ke dalam.

13. One application of a magnetic force acting on a current-carrying wire in a magnetic field is the operating principle of most speakers in sound systems. Explain briefly how it works.
Magnet pada speaker berfungsi untuk mengubah energi listrik menjadi energi bunyi. Prinsipnya adalah magnet sebagai sumber medan magnet. Saat terdapat suara, speaker akan menghasilkan medan elektomagnet yang akan bertabrakan dengan medan magnet. Saat terjadi tabrakan inilah timbul getaran pada frekuensi tertentu yang dapat kita dengar.
PembahasanMagnet dapat dimanfaatkan untuk aktivitas sehari-hari. Salah satu pemanfaatan magnet adalah pada speaker atau pengeras suara. Pada speaker terdapat kombinasi antara magnet permanen dengan elektromagnetik. Adanya magnet membantu perangkat speaker dalam mengubah energi listrik menjadi energi bunyi.
Komponen elektomagnetik pada speaker memiliki kumparan yang biasa disebut voice coil.Voice coil ini berfungsi untuk membangkitkan medan magnet sehingga dapat menggerakkan cone speaker. Saat terdapat sinyal listrik yang melewati voice coil, akan terjadi perubahan pada arah medan magnet. Perubahan gerak ini menimbulkan gerakan tarikan dan tolakan dengan magnet permanen. Gerakan tarikan dan tolakan inilah yang menggerakkan cone speaker sehingga menghasilkan suara yang dapat kita dengar.
