Magnetohydrodyamics (MHD) is the study of the effects of magnetic fields on fluid dynamics. Primarily it is applied to models of the Sun's interior. We know the Sun is in a fluid state and has a global magnetic field as well as strong, localized magnetic flux tubes (think tubes of very high strength magnetic fields). Most models of the Sun ignore the magnetic effects primarily because they are relativiely weak compared to the overall convective/radiative effects. But it is precisely the magnetism that creates sunspots, prominences, and importantly for us solar flares.
In simplest terms, the interior of the Sun has several different regions in which different energy transport phenomenons (phenomena?) work. In one of these layers, huge convection cells transport energy through mass motion (think boiling pot of water). Also note that since the Sun is in a fluid state, different parts rotate at different speeds. This can cause a lot of twisting of the internal magnetic fields, coiling them up into tubes. At the boundary between convection layer and the one underneath, the coiled magnetic fields are "dragged" to the surface by the convection. Where they break through the surface they create sunspots, prominences, and flares.
As we create a larger and larger human presence in space understanding and hopefully predicting solar flares is crucial. You have already probably heard about solar flares disrupting communications satellites. But there is a far more important issue. If we want to have MANNED missions in space, solar flares, which are bursts of high energy radioactive particles, can be deadly. Being able to predict solar flares will be as crucial to space travel as being able to predict hurricanes and tornados is to ground and air travel.
The reason magnetic fields are mostly ignored is that they are darn difficult to model. Fluid dynamics is difficult already, adding in the effects of magnetic fields (which tend to involve vector cross-products in the equations) makes it REALLY tricky. It is a hot area of computer modeling now in astrophysics.
I hope that helps, feel free to ask about any more details or anything that I wasn't clear on. As far as the love thing, that is far too difficult for my feeble brain to understand.
I have a joke for you in the same vein as yours.
A Husband takes his wife to play her first game of golf. Of course, the wife promptly hacked her first shot right through the window of the biggest house adjacent to the course.
The husband cringed, "I warned you to be careful! Now we'll have to go up there, find the owner, apologize and see how much your lousy drive is going to cost us."
So the couple walked up to the house and knocked on the door. A warm voice said, "Come on in." When they opened the door they saw the damage that was done: glass was all over the place, and a broken antique bottle was lying on its side near the pieces of window glass.
A man reclining on the couch asked, "Are you the people that broke my window?"
"Uh...yeah, sir. We're sure sorry about that," the husband replied.
"Oh, no apology is necessary. Actually I want to thank you. You see, I'm a genie, and I've been trapped in that bottle for a thousand years. Now that you've released me, I'm allowed to grant three wishes. I'll give you each one wish, but if you don't mind, I'll keep the last one for myself."
"Wow, that's great!" the husband said. He pondered a moment and blurted out, "I'd like a million dollars a year for the rest of my life."
"No problem," said the genie. "You've got it, it's the least can do. And I'll guarantee you a long, healthy life!" "And now you, young lady, what do you want?" the genie asked.
"I'd like to own a gorgeous home complete with servants in every country in the world," she said.
"Consider it done," the genie said. "And your homes will always be safe from fire, burglary and natural disasters!"
"And now," the couple asked in unison, "what's your wish, genie?"
"Well, since I've been trapped in that bottle, and haven't been with a woman in more than a thousand years, my wish is to have sex with your wife."
The husband looked at his wife and said, "Gee, honey, you know we both now have a fortune, and all those houses. What do you think?"
She mulled it over for a few moments and said, "You know, you're right. Considering our good fortune, I guess I wouldn't mind, but what about you, honey?"
You know I love you sweetheart," said the husband. I'd do the same for you!"
So the genie and the woman went upstairs where they spent the rest of the afternoon enjoying each other. The genie was insatiable. After about three hours of non-stop sex, the genie rolled over and looked directly into her eyes and asked, How old are you and your husband?"
"Why, we're both 35," she responded breathlessly.
"No Kidding," he said. "Thirty-five years old and both of you still believe in genies?"
"Recollect me darlin, raise me to your lips, two undernourished egos, four rotating hips"
