Electromagnetic induction ne eddy current effect: Sɛ alternating current fa biako mu-core cable a, magnetic field a ɛsesa no yɛ generated twa cable no ho hyia. Sɛ saa nhama yi fa dade paipu mu, esiane sɛ dade paipu no yɛ conductor nti, magnetic field a ɛsesa no bɛma electromagnetic induction aba dade paipu no mu, na afei eddy currents no bɛyɛ wɔ dade paipu no mu. Eddy currents no nam electron a ɛnyɛ hwee a ɛwɔ dade paipu mu no so na ɛba wɔ magnetic field nkɛntɛnso ase. Saa adeyɛ yi di anyinam ahoɔden na ɛma dade afiri no yɛ hyew. Sɛ ɔhyew a ɛboro so wɔ hɔ a, ebetumi de ahobammɔ ho nsɛm te sɛ ogya aba.
Magnetic fields a ɛwɔ current directions a ɛne no bɔ abira no twa wɔn ho wɔn ho mu: sɛ wɔde cables pii a ɛwɔ circuit koro no ara mu (te sɛ phase lines abiɛsa ne neutral line biako wɔ abiɛsa-phase four-wire system) mu no bom fa paipu no mu bom, esiane wɔn current directions a ɛne no bɔ abira nti a, magnetic fields a wɔayɛ no bɛpopa wɔn ho wɔn ho, na ɛnam saa kwan yi so no, centdy curmpes a ɛho hia biara bɛba wɔ dade no mu. Nanso, esiane sɛ single-core cables wɔ conductor biako pɛ nti, magnetic field a wɔyɛ no, conductors afoforo ntumi ntwa mu, enti eddy current effect no bɛda adi kɛse.
