Description

So I have attached an image named “Task” which gives a full explanation of how the lab report should be.

Secondly, you can download the images “LabManual1-5” and read them for the lab report.

I also provide a 17 minutes YouTube video that my teacher goes full-on depth on how the assignment should be. Please make sure you watch this one specifically.

Additionally, this 2 video below will do the actual lab live on the video and explain how it’s done.

I need the report to follow the “task” image, video of the lecture, and the instructions I give below. (they are mostly the same thing)

1) the First page just cover

2) The second page will be the introduction, All you have to do for this page is to put the INTRO on the lab manual in your own words. DO NOT COPY AND PASTE

3) the Third page will be similar to the second page however you have to put the procedure section in the lab manual in your own words. DO NOT COPY AND PASTE

4) please follow the “task” image, the part about Data/Analysis, and or the youtube video

5) please follow the “task” image, the part about Conclusion, and or the youtube video

I will tip base on the amount of work you have done and your great writing skills. I like to think I tip decently6 attachmentsSlide 1 of 6

Place the magnet assembly on the balance and position the lab stand so that the horizontal part of the current loop sits between the poles of the magnet (see Figure 9-4), and the plane of the current loop is parallel to the magnet poles.

It may be necessary to readjust the height of the main assembly if the vertical position of the magnet assembly has changed. 9 9-2 LABORATORY OBJECTIVES Determine how the force on a length of current-carrying wire in a magnetic field varies with 1. Amount of current 2. Length of wire Optional: Determine the force on a current-carrying conductor in a magnetic field of a solenoid.) THEORY A current-carrying wire in a magnetic field experiences a force. This force is described by the Lorentz force equation, F = 1L XB (1) where I is the current, L. is the length vector in the same direction as the current), and B is the magnetic field vector. The magnitude of this force is expressed as F – ILB sind (2) where is the angle between the length and the magnetic field vectors (Figure 9-1). Throughout this experiment, the magnetic field will be perpendicular to the direction of current flow, and Equation 2 reduces to: F-ILB (3) The current will flow through several prefabricated current “loops” (wires) suspended in a magnetic field, with the force on the wire measured on a balance.

Select a current loop (see Figure 9-2) with one of the longer lengths, either 6.0 cm (SF 41) or 8.0 cm (SF 42) and record this length.

Place the magnet assembly on the balance and position the lab stand so that the horizontal part of the current loop sits between the poles of the magnet (see Figure 9-4), and the plane of the current loop is parallel to the magnet poles. The current loop should not touch the magnet 4. With no current flowing through the current loop, record the mass of the magnet holder and magnet. It may be necessary to readjust the height of the main assembly if the vertical position of the magnet assembly has changed. 9 9-4 5. Set the current to 0.5 Amps as read on the multimeter. Measure and record the “new mass” of the magnet assembly. (NOTE: With current flowing, the reading on the balance will be higher or lower than before, depending on the direction of the current. The difference in mass is proportional to the force exerted by the current- carrying wire on the magnet assembly.) 6. Increase the current in 0.5 Amp increments to a maximum of 5.0 Amps, each time recording the new mass.” WARNING: Do not exceed 5.0 amps as you will damage the current loop! 7. Shut off the power supply. Heyde FIGURE 9-4. Current loop positioned between the magnet poles. Analysis 1. For each current, determine the “net mass” by finding the difference between the mass of the magnet assembly with current and without current. 2. For each current, find the net force exerted on the magnet assembly by the current- carrying wire by converting your net masses into net weights. 3. Plut a graph of magnetic force versus the current. Find the magnetic field strength of the magnet assembly from the slope. Recall that B is not equal to the slope, but related to it; call this value B Current Balance 9-5 Part B: Force versus Length 1. Without dismantling the setup from the previous part, set the current to 2.0 Amps as read on the multimeter. 2. Record the mass reading for this length 3. Shut off the current. 4. Swing the main arm of the main unit up to raise the current loop out of the mag- netic field. Gently pull the current loop from the arms of the base unit and replace it with a new current loop of a different length. Measure the length of the horizontal section of the loop, according to the diagram in Figure 9-5. Note that some of these lengths have been effectively doubled (eg, loops SF 41 and SF 42). MILLE FIGURE 9-5. Lower section of current loop illustrating the method for measuring the wire length. 5. Carefully lower the arm to reposition the current loop in the magnetic field. 6. Increase the current again to 2.0 Amps and record the mass reading 7. Repeat steps 3 through 6 until all six current loops have been used. 8. Shut off the power supply, Analysis 1. Determine the “net mass” by finding the difference between the mass of the magnet assembly with current and without current. 2. Find the net force exerted on the magnet assembly by the current-carrying wire by converting your net masses into net weights. 3. Plot a graph of magnetic force versus length. Find the magnetic field strength of the magnet assembly from the slope and call this value B, 4. Compare B, and B. to see if they agree within the limits of uncertainty 9
