squirrely2005 Aug 26, 2011 Texas. From what I understand a pint is 16 ounces. I learned that from drinking Busch while living with my dad a few years ago. It just hit me the other day that I have a few glasses that are pint glasses but pouring a 12 ounce beer in them basically fills it up.
Hans Christian Oersted. In 1820, a Danish physics teacher observed that the current moving through a wire moved the needle on a nearby compass. when the current was reversed, the compass needle was deflected in the opposite direction. these magnetic effects ceased when the current in the wire stopped.
If the electric field points in such directions, then how does the field push the charges to the positive terminal? Those are field lines in a vacuum. The field lines are altered when you put in other objects; so with a conducting wire-circuit, the field lines are actually running through the wire (part of what makes a good conductor a good conductor).
