1-A compass is held horizontally. The silver end of the needle points towards geographic south and the blue end points towards geographic north. The compass is then brought near one pole of a horseshoe magnet. The blue end of the compass points towards this pole. What is the polarity of this pole on the magnet?
2-Two bar magnets are arranged so that the ends face each other in a line as shown below. At the spot “x”, the north pole of a compass needle points to the right (east). In what direction will the compass needle point when it is placed at position ‘y?’
1) magnetic north pole will be towards geographical south pole, therefore blue end is south pole. The opposite poles of magnets attract each other, therefore horse shoe is north pole
2) magnetic fields at X and y are in opposite directions, therefore at y, direction of needle will be towards west.

Two bar magnets are arranged so that they are parallel to each other. In case 1, north poles face each other on the right side. In case2, south poles face each other on the right side. In what way is the resulting field pattern the same, and in what way is it different? 2-A bar magnet is placed on a flat surface so that the north pole is on the left side and the south pole on the right. At...
Two bar magnets are arranged so that they are parallel to each other as shown below. The dot at the location shown is the place where a compass is paced. a) If the north end compass needle is to point towards the left (west), what must be the polarity of the poles at “x” and at “y?” b) If the north end of the compass points up (north) at the location of the dot, what must be the polarity of...
nt FULL SCREEN PRINTER VERSION NEXT Cnapter 41, ProDiem b2 A smail compass is held horizontally, the center of its needle a distance of 0.240 m directly north of a long wire that is perpendicular to the earth's surface. When there is no current in the wire, the compass needle points due north, which is the direction of the horizontal component of the earth's magnetic field at that location. This component is paraliel to the earth's surface. When the current...
1. The stack of magnets works as one big bar magnet. Do the poles change when you divide the magnet into pieces? 2. In step 3 of the experiment, do both sides of the magnet attract the metal surface? Explain how a single magnet can repel the rest of the stack, but still stick to the other surface. 3. How does the magnet attract something that is originally non?magnetic? 1. Describe the direction of the compass needle as you moved...
