1. two magnetic north poles will do which of the following? a. attract one another b repel one another c. attract or repel one another, depending on orientation d. not interact with one another 2 magnetic monopoles have never been found in nature nor been created because of this scientists believe that magnets must a. form closed loops b decrease in strength over time c have both north and south poles d be created by moving charged particles 3 what must be true about the domains in a powerful iron magnet a there’s are very few of them b most atoms are magnetically aligend c the domains have been forced out of the magnet d additional domains have been created by the magnetic field 4 which of these will be affected by a magnetic field? select all that apply a moving proton b stationary proton c moving bar magnet d stationary bar magnet 5 magnetic domains are which of the following? a a type of magnetic pole b created by stationary chargers c regions within some types of magnetic materials d a way to prevent magnetic field form entering a region 6. the left side of magnet x is attracted to one end of magnet x and also to one end of magnet y. what is the polarity of the left side of magnet x? a north b south c either north or south 7 what is the relationship between the auroras and earth magnetic field a the auroras are earth”s magnetic field b the auroras create earth magnetic field c earth magnetic field create the auroras d streaks in the sky correspond directly to earth magnetic field line 8 which of the following could be the cause of the magnetic properties of a bar magnet a vibrating magnetons within the magnet b molten metal convecting inside the magnet c open magnetic field lines entering the magnet d electrons moving inside the atoms of the magnet 9 earth magnetic field is similar to that of a bar magnet. select all the statements that are true as a consequence of this a it has a north and south magnetic pole b it has a bar shaped iron section inside it c its magnetic field lines form closed loops d magnetic object are attracted to its poles
