Hello,
From what I know,
When an alternating voltage is applied to an air coil, a current flows which lags by 90 degrees. A flux will develop which is in phase with the current. This changing flux will develop an emf which opposes the applied voltage meaning 180 degrees phase difference.
Now if I place another coil next to the original coil, a emf will be induced into that coil. That as stated is 180 from the applied voltage but on your website, it says that it will be in phase with the applied voltage...?
