Current Balance and Accessory Introduction A current-carrying wire in a magnetic field experi- With the PASCO SF-8607 Basic Current Balance, you ences a force that is usually referred to as a magnetic can vary three of the variables in the equation—the force.
• Magnet Assembly with six magnets. Additional Equipment Needed: Additional Equipment Needed: • The Main Unit from the SF-8607 Basic Current In addition to the included equipment, you will need Balance plus additional equipment as listed above the following items to perform the experiments in this under additional equipment for the SF-8607.
If you are using a top-loading electronic balance: Figure 3 Setting Up the SF-8607 Basic Current Balance With the Magnet Assembly sitting on the balance, tare Mount the Main Unit on a lab stand having with a rod the reading by pressing the appropriate switch on the 3/8 inch (1.1 cm) in diameter or smaller.

Current Loop in the magnetic field. Six Current Loops are The magnetic field is varied by changing the number of supplied with the SF-8607 Basic Current Balance magnets that are mounted on the Magnet Assembly. (We Kit. The lengths are: recommend you mark the north pole of each magnet, to help students during setup.) The magnetic field strength...
012-04046C Current Balance and Accessory Experiment 1: Force versus Current Procedure If you're using a quadruple-beam balance: Set up the apparatus as shown in figure 1.1. Current Loop Determine the mass of the magnet holder and magnets with no current flowing. Record this value in the column under “Mass”...
Current Balance and Accessory 012-04046C Experiment 2: Force versus Length of Wire Procedure Set up the apparatus as in Figure 2.1. Current Loop Determine the length of the conductive foil on the Current Loop. Record this value under “Length” in Table 2.1. Main Unit Magnet If you are using a quadruple-beam balance:...
012-04046C Current Balance and Accessory Experiment 3: Force versus Magnetic Field Procedure Set up the apparatus as shown in Figure 2.1. Use the shortest length current loop. If you are using a quadruple-beam balance: Mount a single magnet in the center of the holder. With no current flowing, determine the mass of the Magnet Assembly.
Current Balance and Accessory 012-04046C 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 Main Unit no current flowing. Record this value in Table 4.1 SF-8608 on the appropriate line.
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.
