Objectives for Quiz #1
[1] Know what is meant by the term permanent magnet. Be able to describe how a permanent magnet interacts with other objects. Be able to describe a procedure for determining whether or not an object is a permanent magnet.
[2] Know what is meant by the term ferromagnet. Be able to describe how a ferromagnetic material interacts with other objects. Be able to describe a procedure for determining whether or not an object is made of a ferromagnetic material. Be able to give an example of a ferromagnetic material.
[3] Know what is meant by the term magnetic pole, and know how the north pole of a magnet is defined.
[4] Be able to describe a procedure for determining whether a certain magnetic pole is a north or south pole.
[5] Know how many different types of magnetic poles there are. Know how many different poles a single magnet may have, and know what kinds of poles a single magnet may have.
[6] Know how different magnetic poles interact with each other, and with other materials.
[7] Be able to describe a procedure for locating the poles of a magnet.
[8] Understand the difference between Magnetic North and True North. Be able to explain why they are not the same here in East Stroudsburg.
[9] Understand how the strength of the magnetic interaction between two objects depends on the distance between them.
[10] Be able to describe a method for determining the relative strengths of the poles of two different magnets.
[11] Be able to predict how a stack of magnets will behave when the magnets are stacked pole to pole, with opposite poles of adjacent magnets touching.
[12] Be able to predict how a stack of magnets will behave when the magnets are stacked pole to pole, with identical poles of adjacent magnets touching.
[13] Be able to predict how a stack of magnets will behave when the magnets are stacked side to side (as opposed to pole to pole).
[14] If a permanent magnet is divided by cutting it along a line perpendicular to the one joining its poles, be able to predict how each of the two pieces will behave magnetically.
[15] If a permanent magnet is divided by cutting it along a line parallel to the one joining its poles, be able to predict how each of the two pieces will behave magnetically.
[16] Know what an Operational Definition is, and be able to provide one if asked!
[17] Know what a magnetic field is. In particular, know how the direction of a magnetic field relates to the behavior of a compass.
[18] Given a magnet with the pole locations labeled, be able to sketch what the magnetic field looks like.
[19] Be able to complete objective [18] above when multiple magnets are present.
[20] Know that most ferromagnetic materials become magnetized (that is, they turn into permanent magnets) when they are left in proximity to a permanent magnet for a while. Be able to predict where the north and south poles of the magnetized ferromagnet will form.
[21] Know that an electric current produces a magnetic field.
[22] Know what the magnetic field produced by a straight, current-carrying wire looks like.
[23] Know what the magnetic field produced by a current-carrying wire wrapped around a nail looks like. Be able to predict which side of the nail will act as a north pole, and which will act as a south pole when the current is flowing.
