W \\_ Example: '- " It a coil conductor is connected to a 3 kn resistor, what wouid be the rated voltage and current that would be measured if the north pole of the magnet is moving closer to the coil conductor and the rate of change of flux is 3 wbis and the number 01 turns is three? ;' " '_ Given: n n I" l- ' N= 3 turns m, Figure 1. (a) When this bar magnet is thrusted into the = 3 WW8 soil the strength at the magnetic field B' masses in the coil The current induced III the coil creetes another eld. R: 3RD: 3x1030 Elf-m intheopposiefdirectionotmebarmagnetstooppose the Increase This Is one aspect of Lenz' s lawinduction Solution: opposes any change in flux (b) and {c} are two other (1'? WI) 9 =Ndt=(3)(3)=9V By [allowing Fig. 1 {a} it can be seen that the motion of the magnet makes the induced current move -m clockwise. therefore mak'ng the measured voltage situations. Verity tor yourself that the direction of the hduoed Ecol! shoIIIIn indeed opposes the change in ux 14 and that the current direction shown is consistent wilt the right-hand rule in Attachment A.1. positive. . By Ohm's Law where V = e: CONCIUStOUI V e 9 V Therefore. the rated voltage across the resistor is 9 V and I = = i = 3 x 103 = 3 x 104A er 3 not the rated current passing through the resistor is 3 mA. Activity: Solve tor the rated current and rated voltage. on the given gure. when the number of turns of the conductor is eight {8) and the rate of change is 4 was on the given situations; (a) the south pole of the magnet is moving towards the coil conductor and (b) the south pole at the magnet is moving away from the coil conductor. Write your answers on a separate sheet of paper and illustrate the direction of the current. Use the rubrics as your guide in presenting your solution (refer to attachment A2 at the next page)
