012-04046C Current Balance and Accessory Introduction With the PASCO SF-8607 Basic Current Balance, you can vary three of the variables in the equation—the current, the length of the wire, and the strength of the magnetic field—and measure the resulting magnetic force. By adding the SF-8608 Current Balance Accessory, you can also vary the angle between the wire and the magnetic field, thereby performing a complete investigation into the interaction between a current carrying wire and a magnetic field.
012-04046C Current Balance and Accessory Equipment The SF-8607 Basic Current Balance The SF-8608 Current Balance Accessory Your SF-8607 Basic Current Balance includes the items shown in Figure 1: Your SF-8608 Current Balance Accessory includes the items shown in figure 2: • Main Unit, • six Current Loop PC boards • Magnet Assembly with six magnets. • the Current Balance Accessory Unit • Magnet Assembly.
012-04046C Current Balance and Accessory Operation The SF-8607 Basic Current Balance If you are using a quadruple-beam balance: To set up the Current Balance (see Figure 3): First measure the weight of the Magnet Assembly with no current flowing (F0). Then turn on the current, adjust it to the desired level, and measure the weight of the Magnet Assembly with current flowing (FI). With current flowing, the reading will be higher or lower than before.
012-04046C Current Balance and Accessory Varying the Magnetic Field carefully lower the arm to reposition the Current Loop in the magnetic field. Six Current Loops are supplied with the SF-8607 Basic Current Balance Kit. The lengths are: Current Loop Length SF 40 SF 37 SF 39 SF 38 SF 41 SF 42 1.2 cm 2.2 cm 3.2 cm 4.2 cm 6.4 cm 8.4 cm The magnetic field is varied by changing the number of magnets that are mounted on the Magnet Assembly.
012-04046C Current Balance and Accessory Experiment 1: Force versus Current Procedure If you're using a quadruple-beam balance: ➀ Set up the apparatus as shown in figure 1.1. ➁ Determine the mass of the magnet holder and magnets with no current flowing. Record this value in the column under “Mass” in Table 1.1. Current Loop Main Unit ➂ Set the current to 0.5 amp. Determine the new “mass” of the magnet assembly. Record this value under “Mass” in Table 1.1.
012-04046C Current Balance and Accessory Experiment 2: Force versus Length of Wire Procedure ➀ Set up the apparatus as in Figure 2.1. Current Loop ➁ Determine the length of the conductive foil on the Current Loop. Record this value under “Length” in Table 2.1. Main Unit If you are using a quadruple-beam balance: ➂ With no current flowing, determine the mass of the Magnet Assembly. Record this value on the line at the top of Table 2.1. Lab Stand ➃ Set the current to 2.0 amps.
012-04046C Current Balance and Accessory Experiment 3: Force versus Magnetic Field Procedure ➀ Set up the apparatus as shown in Figure 2.1. Use the shortest length current loop. If you are using a quadruple-beam balance: ➁ Mount a single magnet in the center of the holder. ➂ With no current flowing, determine the mass of the Magnet Assembly. Record this value in the first column under “Mass” in Table 3.1 on the appropriate line. ➃ Set the current to 2.0 amps.
012-04046C Current Balance and Accessory Experiment 4: Force versus Angle Procedure 1. Set up the apparatus as shown in Figure 4.1. If you are using a quadruple-beam balance: 2. Determine the mass of the Magnet Assembly with no current flowing. Record this value in Table 4.1 on the appropriate line. Main Unit SF-8608 Accessory Unit 3. Set the angle to 0o with the direction of the coil of wire approximately parallel to the magnetic field. Set the current to 1.0 amp.
012-04046C Current Balance and Accessory Maintenance STORAGE CUSTOMER SERVICE (see Figure 9) For service problems, please call (toll-free 1-800-772-8700) and ask for customer service. When storing your SF-8607 Basic Current Balance, we recommend that you alternate the magnets so they have their north poles next to south poles for maximum retention of field strength.
