The fundamental theorem of #vectorcalculus states that any vector field can be expressed as the sum of an #irrotational and a #solenoidal field. The condition of zero #divergence is satisfied whenever a vector field v has only a vector potential component

"Well, THERE'S yer problem. Ya got a bad #hickendorffer #solenoidal relay to yer pickle-dipple feed enforcer. Unless ya got a #merble fleegle flange reducer, yer #mingtinglingle ain't gonna spark up yer #Torque twaddler."
Sir, I am a tweedy academic, despite how I look. All I know is "car no go vroom vroom."
