We know that a day is actually 23 hours 56 minutes and 4 seconds long. That means If sunrises at 6 a.m this morning, tomorrow it will rise at about 4 minutes earlier. In two month the sun will rise 4*60 minutes= 4 hour earlier, i.e at 2 a.m. It is unusual, so something must be wrong!
What is the flaw in the above analysis?

I took apart a few electronic devices and I noticed that the electromagnet in them (or solonoid) had bare copper wire wrapped around an insulated metal. Are electromagnets more effective if the wire wrapped around isnt insulated? If so, does the core need to be insulated? If I had made an electromagnet using a stell nail and wire, the nail would become the magnet. Some electromagnets I have looked at have the metal part not just as the core, but also on the sides of the magnet, why?

a comparison table would be good. I'll start the table (plz don't make your own, just add to mine). Add stuff to either or both sides. i'll probably put it up to a vote.

A permanent magnet has a north and south and if you put two norths together or two souths together, they will repel. I have noticed that an electromagnet doesn't seem to care about north and south poles. In other words, it seems that my electromagnet is only one directional. Are electromagnets polarized? Can you make an electromagnet repel a permanent magnet?
