Medan Magnet - Definisi, Rumus, Pengertian, Contoh Soal dan Pembahasan

Adanya medan magnet di dalam ruang dapat ditunjukkan dengan mengamati pengaruh yang ditimbulkan.

• Bila di dalam ruang tersebut ditempatkan benda magnetik maka benda tersebut mengalami gaya.


• Bila di ruang terdapat partikel/benda bermuatan, maka benda tersebut mengalami gaya.

 

• Medan magnet merupakan besaran vektor,
adapun kuat/lemahnya medan tersebut ditunjukkan oleh intensitas
magnet (H).

• Efek medan magnet disebut induksi magnetik (B),
juga merupakan besaran vektor.

• Hubungan antara H dan B :

B = m_o H

dengan :

B = induksi magnetik, satuan dalam SI = Weber/m² atau Tesla
H = intensitas magnet
m_o = permeabilitas = 4p x 10^-7 Wb/A.m (udara)
