magnetic field lines are from north pole to south pole outside a bar magnet but its direction is from south pole to north pole inside it. Why and what causes it?
So basically , we all know the direction outside the magnet its from NORTH to SOUTH. but what i don't understand is that what is the direction inside is it the same ??
Is it consistent with ZF for there to exist a set $S$ such that the power set $P(S)$ is countable? If so, what is the weakest form of the axiom of choice needed to prove that no such set exists?

Sending an E-mail to all addresses of all contacts in a contact group in Gmail I'm trying to send an E-mail message using Gmail to a contact group where some of the contacts have more than one E-mail address and I want to send the mail to all of them.   Is there a way for me to do that? I see ads to other SE sites regularly on the sidebar of SO. Are these questions chosen by hand, or algorithmically? The reason I ask is that there was an ad pointing to  on Seasoned Advice. I'm all for a good laugh I suppose, but is this the kind of question that should be highlighted?  It's obviously a thriving community, but if this were my first exposure to that community, and I saw that the highest-rated answer -- from the user with the highest reputation -- was (and I paraphrase only lightly):  &quot;Why yes, there is tool that can cut cherry tomatoes in half.  It's fantastic for the job.  It's called a freakin' KNIFE!&quot;  would I ever want to visit again, let alone ask a question over there? First impressions count for a lot, and that one missed the mark IMHO. If the selection method is algorithmic, I suppose there's no reliable way to detect sarcasm in a highly-rated answer, but if it's manual, weeeellllllllll ... :) GNU find and masking the {} for some shells - which? So this is a question with which I have been stuck for a while and it all revolves around the concept of volt.  I have posted a LOT of questions on physics forums while trying to understand the concept of volt and potential difference. This is hopefully going to be the last one.  What do you exactly mean when you say that a battery is 2.5 V. I know that it says that the potential difference between the 2 terminals of the battery is 2.5 V  but then what is the potential of the 2 ends of the battery? Is there a unit of potential and not just potential difference?  Also volt = work/charge but how can work/charge express the difference of potentials across the 2 terminals? Global setting of hyphenation for words containing dashes The official deck construction rules for Commander (nee EDH) at  say that 'A card's colour identity is its colour plus the colour of any mana symbols in the card's rules text.'  How does this apply to dual-faced cards with faces of different colors, such as  out of Innistrad or  from Dark Ascension, where the color of the transformed face of the card is different from the color of the 'main face'?  The spirit of the rules would seem to suggest that these cards are the colors of both faces for deck construction purposes, but not only are these spells always cast as the front face, the front face is the only one 'seen' in other game zones: for instance, when the card's in the library, you could find Elbrus by searching your library for an artifact, but you couldn't find Withengar Unbound by searching your library for a creature card.  Could Elbrus then, for instance, be played in any Commander deck, or just one with a (partly) Black general?

Hide a Field From ONE User Scenario: If I had a Custom Profile / Standard Profile, say Sales,and I have 50 Users assigned to the same Profile and had same Permission / Access on a particular object (Could be Standard or Custom Object), if I were to Hide a Field ONLY TO ONE USER, which would be  a better Solution to achieve this WITHOUT EDITING OR TOUCHING THE PROFILE??  Option 1: Create a Custom Profile for this particular User and give CRED access (I know this one isn't a good solution as I got a Thumbs-down from a Technical Architect)  Option 2: Create a Permission Set - Go to the particular Object,say, Accounts, Object Permission Enabled -->Field Permissions-->Remove READ Access - This would make this particular field hidden from the Object to the Profile. Then Assign this Permission to particular User whom I don't want to see this field.  I would go with the 2nd option but I still hear a groan. Where am I going wrong? How would you hide a particular field from ONE User out of 10 Profiles who have the same Access Rights?  What's the best possible solution to hide a Filed from only one User out of 10 Users who have the same Profile. If light is an electric and (magnetic field), how can it be absorbed? I was wondering how light or any electromagnetic radiation can be "absorbed" if it consists of electric and magnetic fields. For example if there is a charge at point A, and the  light reaches point A, it will cause that charge to move depending on the value of the electric field. However, why wouldn't this electric field continue on and influence others particles everywhere else? For example, if you have a static charge creating an electric field, then if you put a charge at point A it will feel its effects and then if you bring a charge at another location B it will also feel its effects, namely it will not have been absorbed. Please shed some light on this. Thanks  edit: Does this mean the electron that absorbs this light moves in such a way that it creates an electric field of its own canceling the initial one? Or am I way off? How can I intercept XMLHttpRequests from a Greasemonkey script? I got 2 ghast tears after I thought I deflected a fireball back at the ghast (with my looting 3 sword).  But I was pretty close, so I might have just hit it. I'm not sure.  If I deflect a fireball with a looting sword and it kills the ghast, do I still get the looting bonus? I have recently noticed a rather large amount of small worms in the fresh cod I am buying. I have tried to take them out as much as I can and of course have spoken to my fish supplier about them, but he assures me they are harmless. However, I don't believe my customers would be as assured. Is it okay to serve this fish, taking into account I might miss a worm or two? A stochastic process is a process that evolves over time, so is it really a fancier way of saying "time series"? How might I schedule a C# Windows Service to perform a task daily? I have a service written in C# (.NET 1.1) and want it to perform some cleanup actions at midnight every night. I have to keep all code contained within the service, so what's the easiest way to accomplish this? Use of Thread.Sleep() and checking for the time rolling over? In high school we learned to say "than I" and "as I" because you could potentially add an "am" to the end of the sentence.  Examples:  "She is smarter than I."  (Think: "...than I am.") "He is as tall as I."  (Think "...as I am.")  So analogously, shouldn't it be "like I" as well:  "He is sincere, just like I."  (Think: "... like I am.")  But universally, it seems that we use "like me".  Where does this reasoning break down?  Is there history here? I would like to know the model of my graphics card.
