Experiment 9 Electromagnetic Induction "Concepts without factual content are empty; sense data without concepts are Your lab station is also supplied with some coils, a magnet, a current source, and a compass to determine the direction of the fields. Since the galvanometer is very delicate, it is easily damaged by excessive current. Faradays law experiment. 1 Results and discussions Part A: By taking figure 2 experimental setup as reference, the direction of B is outside the page and the direction of potential Airgap is negative when the current is positive and decreasing. The direction of B is into the page and the direction of potential Airgap is negative when the current is negative and increasing. Jun 28,  · Electromagnetic Induction PHY Lab Report Electromagnetic Induction Your Name: Sathi Das Partner’s Name: Ancy Daniel and Trinh Nguyen Date Performed: 11 March Date Due: 18 March Instructor: Huta Banjada Introduction The purpose of this experiment was to test with different variables concerning electromagnetic induction which is the link between electricity and 97%(35).



The direction of B is into the page and the direction of electromagnetic induction lab report Airgap is negative when the current is negative and increasing. The direction of B is outside the page and the direction of potential Airgap is postive when the current is negative and decreasing.

When static current is used, this means that the current is not changing with the time due to the flow of electric charge is only in one direction. Hence, the potential Airgap will be zero and there will be no direction of B because the current is not changing and thus there is no induced emf as well as magnetic charges. Faradays law experiment 2 Figure 1: Geometry of twisted wire pair of problem Q4. The direction of surface in loop 2 anti-clockwise and outside the page.

Due to the direction of flux of loop 1 and loop 2 are opposite. While passing by with each other, the flux will be cancelled out. Hence, the net flux is equals to zero. The interference will be decreases because the loop area between wires is reduced. Faradays law experiment 3 c If parallel wires are used instead of twisted wires, the parallel wires will carry currents that will exert forces to each other.

The force is attractive if the current goes the same way in both wires. If the currents are on the opposite direction for both wires, the force will be repulsive instead. By using parallel wires, one of the wires will set up magnetic field and then another wire will be influenced by the magnetic field. Crosstalk such as noise and interference will occur. Moreover, electromagnetic induction lab report, parallel wires only include low bandwidth that can be transmitted.

Hence, electromagnetic induction lab report, if parallel wires are used instead of twisted wires, there will be electromagnetic interference and noise occurs. Faradays law experiment 4 4. Please make sure that the connections are as shown in figures 4. Faradays law experiment 5 Theoretical results Table 3: Theoretical value of potential air gap for loop 1 Frequency kHz Theoretical mv Phase shift deg 10 3.

Table 4: Theoretical value of potential air gap for loop 2 Frequency kHz Theoretical mv Phase shift deg 10 4. Faradays law experiment 6 Comparison between experimental and theoretical results for loop 1 and loop 2. This might cause by the current value does not constantly maintain at 0. The other source of error might be due to calibration error of the oscilloscope. Faradays law experiment 8 Question: What is the percentage error for electromagnetic induction lab report shift of this experiment?

Answer: For loop 2, the circuit electromagnetic induction lab report performed for 2 turns because the area for loop 2 is a portion of loop 1, electromagnetic induction lab report. The area of loop 1 is almost twice the area of loop 2. Hence, the value of V loop2 should be multiply by 2 so it is nearer to the electromagnetic induction lab report of V loop1 in order to do comparison.

Faradays law experiment 10 In this experiment, practically, electromagnetic induction lab report partner and I have learnt how to setup the experiment layout by using soldering and connecting the twisted wires to the AC oscilloscope.

Moreover, my partner and I also learnt how to observe the AC waveforms shown electromagnetic induction lab report the oscilloscope to obtain phase shift and the value of potential airgap. By referring to theory, my partner and I have learnt new knowledge application of Faradays law and Lenzs law on magnetic field. Basically, Faradays law is referring to basic law of electromagnetism that the emf induced in the loop should be proportional to the rate of change of magnetic flux through it.

By applying the Faradays law formulae, electromagnetic induction lab report, the voltage over the loop which is known as electromagnetic force emf can be calculated. Furthermore, I also learnt the application of Lenz law on magnetic field.

Generally, Lenzs law states that the induced emf and current will be in a direction such that the induced magnetic field opposes the original magnetic flux change. The induced current will produce an induced magnetic field. The magnetic field will be opposing the direction of the changing flux. The lenzs law can be used to determine the induced emf direction of the loop. Besides that, I also learn how to derive the formulae of induced emf regarding Faradays law and perform theoretical calculation for loop 1 and loop 2.

Finally, the results for both experimental and theoretical results for loop 1 and loop 2 have been compared and contrast for further understanding. Read Free For 30 Days. EE Lab Report Final. Uploaded by Jason Gonzalez. Flag for inappropriate electromagnetic induction lab report. Related titles.
