Flames are ionised (i.e. charged) particles. If you have a strong enough electric field (which is really not the same as 'shooting electricity' as per the article) when the charged particles move through the electric field there will be a force on them perpendicular to their motion and to the field i.e. the flame will curve over into spiral.
That's for a magnetic field. Charged particles move along the direction of electric fields.
Incredibly low? TFA quoted the median salary for a teacher in their mid 30s as $74,000 a year. I'm sure many people would be happy to trade their "incredibly low" salary for that incredibly low salary.
I don't know what article you're reading but the one linked in the summary says nothing about the median salary of a teacher. The number $74,000/yr, which I assume you pulled out of your ass, is about $30,000/yr inflated over the actual value. Sure, after 30 years of teaching I'd be making that much, but not in my mid-30s.
Yet magic and hierarchy arise from the same source, and this source has a null pointer.
