Pfungwa yemagetsi emagetsi

Mu electromagnetism, huwandu hwemagetsi hunopfuura nepakati pechikamu chipi nechipi che conductor panguva imwe neimwe hunonzi current intensity, kana kuti electric current. Chiratidzo che current ndiI, uye unit ndi ampere (A), kana kungoti "A" (André-Marie Ampère, 1775-1836, French physics uye chemist, uyo akaita budiriro huru mukudzidza electromagnetic effects uye akapawo mipiro kumasvomhu nefizikisi. International unit ye ​​electric current, ampere, inotumidzwa zita remhuri yake).
[1] Kufamba kwemahara mu conductor nguva dzose pasi pesimba remagetsi kunoita kuti magetsi ashande.
[2] Mumagetsi, zvinotsanangurwa kuti divi rekuyerera kwemari ye positive charges ndiro divi rekumhanya kwemagetsi. Pamusoro pezvo, muinjiniya, divi rekuyerera kwemari ye positive charges rinoshandiswawo sedivi rekumhanya kwemagetsi. Hukuru hwemagetsi hunoratidzwa nechaji Q inoyerera nepakati pechikamu chemuchina panguva imwe neimwe, iyo inonzi simba remagetsi.
[3] Kune mhando dzakawanda dzezvitakuri zvinotakura magetsi. Semuenzaniso: maerekitironi anofambiswa mumaconductor, maion mumaelectrolytes, maerekitironi nemaion muplasma, uye maquark muma hadrons. Kufamba kwezvitakuri izvi kunoumba magetsi.
