Hydraulic a me ka pneumatic solenoid valve coil K23D-2H

Ke kumu o ka electromagnetic coil-inductance

1. ʻO ke kumu hana o ka inductance, ʻo ia ke hele ʻana o ke au i ka conductor, e hoʻokumu ʻia ka flux magnetic alternating a puni ka conductor, a me ka ratio o ka flux magnetic o ka conductor i ke au e hana ai i kēia flux magnetic.

2. Ke hele nei ka DC i loko o ka inductor, ʻike wale ʻia kahi laina kahua magnetic paʻa a puni ia, ʻaʻole ia e loli me ka manawa; Eia nō naʻe, i ka wā e hele ai ke au i loko o ka coil, e loli nā laina mākia a puni ia me ka manawa. Wahi a ke kānāwai o Faraday o ka electromagnetic induction-magnetic induction, ʻo ka hoʻololi ʻana i nā laina kahua magnetic e hoʻopuka i kahi mana i hoʻokomo ʻia ma nā ʻaoʻao ʻelua o ka coil, e like me ka "mea mana hou".

3. Ke hoʻokumu ʻia kahi loop pani, e hoʻopuka kēia mana i hoʻokomo ʻia i kahi au i hoʻokomo ʻia. Wahi a ke kānāwai o Lenz, ua ʻike ʻia ʻo ka nui o nā laina kahua magnetic i hana ʻia e ka au i hoʻokomo ʻia e hoʻāʻo e pale i ka hoʻololi ʻana o nā laina kahua magnetic.

4. ʻO ka hoʻololi ʻana o nā laina laina magnetic mai ka hoʻololi ʻana i ka mana o waho, no laila mai ka hopena pahuhopu, ʻo ka inductance coil ke ʻano o ka pale ʻana i ka hoʻololi o kēia manawa i ka kaapuni AC.

5. Inductive coil loaʻa nā ʻano like me ka inertia i ka mechanics, a ua kapa ʻia ʻo ia "self-induction" i ka uila. ʻO ka maʻamau, e puka mai nā ʻōlinolino i ka manawa i wehe ʻia ai ka hoʻololi ʻana i ka pahi, ʻo ia ke kumu o ka mana kiʻekiʻe.

6. I ka pōkole, i ka wā e hoʻopili ai ka inductance coil i ka mana AC, e hoʻololi nā laina magnetic i loko o ka coil i nā manawa a pau me ke ʻano o ka manawa, e hopena i ka hoʻokomo electromagnetic o ka coil. ʻO kēia ikaika electromotive i hana ʻia e ka hoʻololi ʻana o ke au o ka coil ponoʻī i kapa ʻia ʻo "self-induced electromotive force".

7. Hiki ke ʻike ʻia ʻo ka inductance he ʻāpana wale nō e pili ana i ka helu o nā huli, ka nui, ke ʻano a me ka waena o ka coil. ʻO ia ke ana o ka inertia o ka inductance coil a ʻaʻohe mea e pili ana i ke au i hoʻohana ʻia.
