Question

b. Place the Magnet Assembly on the Electronic Balance. Zero the reading on the balance, so the weight of the magnet is subtracted from the reading and the force of the current-carrying wire on the magnet is the only force measured by the balance. There will either be a zero function on the balance or a function labeled “tare” to zero the reading. Make sure the lab stand is positioned so that the Current Loop is between the poles of the magnet and not be touching the magnet. With the power supply off, connect the power supply and ammeter as shown in Fig. 2, so that the force on the magnet is downwards and the ammeter will read a positive current when the current is turned on. Turn the Voltage knob on the power supply completely clockwise. The Current knob should be completely counterclockwise. Turn on the power supply. Slowly turn the Current knob clockwise to check if you have correctly connected the power supply and ammeter so that the ammeter reads positive current. If not, turn the current down and the power supply off and check your connections.
