MAGNETISM 2 From the "Magnetic Fields" lecture notes: 1. Draw the symbol for out of the page: For into the page: 2. Which side of a compass is its north pole? 3. A compass needle points toward which pole of a magnet?5. Use the compasses to mark the north and south poles of the bar magnet at the right. [Notice that the compasses point to the right on BOTH sides of the magnet} @_ 9% 9 9] 5. What do we call a magnet suspended above another magnet? T. In the diagram at the right; use the compasses to decide which direction the current owing in the wire: to the right orto the left? I I X K B I I X X I I X K I I X X A wire 5. A. In the diagram at above right, which direction is the magnetic field {E} on the left side of the wire: into or out of the page? B. Which direction is the magnetic field [E51 on the right side of the wire? C. Which direction must the current be flowing in the wire? 9. A. The group of coiled wires at the right is called a s B. Current flowing thru wires causes m C. Ifthe current is moving as shown, which side is north? 1:}. The wire below has electric current flowing into the page. Pointing vour right thumb into the page; which was! is the cur rent flowing: clockwise or counterclockwise? 11. A. Between the two donut magnets which way does the magnetic field (B) point? B. Which way will the north pole of the inner magnet turn? N S 12. A bar magnet as seen at the right, is suspended by a string so that it is free to turn. A. Which part of the compass points toward the north? The hanging magnet will work the same way B. Which side of the magnet points toward the earth's North Pole? C. The magnet stops moving in the position shown, which side of this piece of paper is facing toward the earth's North Pole? D. Therefore, the earth's geographic North Pole is what pole of the earth's internal magnet
