I"! \\. Example: If a coil conductor is connected to a 3 kn resistor, what would 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 wbrs and the number of turns is three? ;' " '_ Given: n n I" l- ' N= 3 turns 1. Figure 1. (a) When this bar magnet is thrusted into the = 3 \"this coil the strength of the magnetic field B' masses in the coil The current induced In the coil creates another eld. R: 3RD: 3x1030 Elf-m intheopposiefdirectionotthebarmagnetstooppose the Increase This Is one aspect of Lenz' s lawinduction Solution: opposes any change in flux (b) and {c} are two other situations. Verity for yourself that the direction of the (14?

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 positive. By Ohm's Law where V = e: e g y Therefore. the rated voltage across the resistor is 9 V and E = m = 3 1 10314 0?\" 3 "1:4 the rated current passing through the resistor is 3 mA. Conclusion: V l__ 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 were on the given situations; (a) the south pole of the magnet is moving towards the coil conductor and (b) the south pole ot 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)
