In this lab we will investigate the magnetic field of the solenoid. Purpose of This Lab The purpose of this lab is to build an electromagnet and determine how the number of coils affects the strength of the magnet. However, the volume outside the solenoid is much greater than the volume inside, so the density of magnetic field lines outside is greatly reduced. The solenoid is a of magnetic field a solenoid lab report, why or disk drives with brief discussion of. 
The end of your compass needle that points toward the magnetic pole of the Earth in the northern hemisphere (when it is far away from any magnet or other magnetic material) is by definition an N pole. Hypothesis Page 1 of8 1 . Our method consists of two procedures: calibration and inspection. In conclusion, although still lack of mechanistical insights, our the earths magnetic field left on the rock remains. Like the electric field, the magnetic field has both a magnitude and a direction. Physics 1051 Laboratory #4 Magnetic Field of a Solenoid Open the switch (power off). If n n is the number of turns per unit length, there are nL n L turns in length L L, therefore the total current enclosed by the closed path is nL n L times I I, that is nLI n L I. So according to Ampere's law we have, The above expression of magnetic field of a solenoid is valid near the center of the solenoid. 2. 2. Question 1. 6.2) states that a voltage e ( t) is induced at the terminals of a coil that "sees" a time-varying magnetic flux. Note the filings follow the field lines which are concentrated in the center of the solenoid where the magnetic field is most powerful. Now recall - After lab, we have determined the relationship between magnetic fields and current in solenoid. Using Ampere's law one can derive the magnetic field inside the solenoid to be B = o n I (1) where = 4 10-7Webers/A m, n is the number of turns per unit length, and I is the current. Figure 1 shows how to use a compass to determine the direction of a magnetic field. For solenoids that are not very long, we use a more accurate formulae for the magnetic field: 1/2B = o 709 Words 3 Pages. Solution: Given: No of turns N = 300. Making a lab report is a kind of chore on a daily basis faced based on the university students. RESULTS CONCLUSION Pin number 3 was selected for both simple digital output as well as for PWM output with different frequencies. PHYS 1493/1494/2699: Exp. The earths magnetic field is about 0.5 G, so it is too small for this sensor to measure. 2. In this lab the magnetic fields surrounding bar magnets are mapped out using a compass and iron filings. Close the switch (power on). This range covers the typical refrigerator magnet (about 200 G) and the typical lab magnet (about 2000 G). A solenoid of diameter 40 cm has a magnetic field of 2.9 10 5 N/Amps m. If it has 300 turns, determine the current flowing through it. If the coil voltage e ( t) is electronically integrated, then. 3 Magnetic Fields 3 Outline Today we will deal with magnetic fields only The physics of interest to understand the experiment is: Interplay between electric currents and magnetic fields: Currents experience magnetic force (Lorentz law) Current generate magnetic fields (Biot-Savart law) The experiment will be mainly focused on: The magnetic field generated by the solenoid is 8.505 10 4 N/Amps m. Example 2. The eld is constant inside the coil away from the ends. With regards to magnetic field line patterns, solenoid patterns turned out to be similar to a bar magnets, while SN-SN configuration produced a constructive field line pattern, which had allowed it to act as a single magnet, and attract each other, while the SN-NS experienced the contrary. Select the AXIAL field by clicking the FIELD SELECTOR SWITCH on the Magnetic Field Sensor. 27/08/2013 Quick Answer PHYSICS 1B Ampere's Law and Magnetic Fields Electricity & Magnetism Magnetism Introduction: includes the theory and purpose of the experiment. -Co (OH) 2 sheets of several micrometers in width and about 20 nm in thickness were reproducibly yielded in the presence of an applied strong magnetic field (2 PHYSIC LAB 9 SOLENOIDS Introduction: This experiment is to help students to measure the magnetic field inside a solenoid based on the current through the solenoid, and to examine Faraday's Law of Induction.
As well as magnetic fields and turns in a solenoid. - Length of slinky affects the turns per meter -As turns per meter increase, so does the Magnetic Field. 3. A solenoid is a coil of wire that is tightly wound into a helical form. Inside the center of the solenoid is a magnetic field that is uniform and parallel to tits axis, except near the end of the solenoid. The magnetic field is only in the center of the solenoid. The magnetic field III. Theory states that the magnetic field produced by a long straight current-carrying wire decreases in strength as you get further from the wire. Solenoid Lab Report; Solenoid Lab Report. Faraday's law (See RWVD Sec.
Results: includes data sheets, calculations, data tables, and graphs. The magnetic field is analogous to the electric field that exists in the space around electric charges. Familiarize Yourself with the Magnetic Field Sensor Make sure that the switch on the magnetic field sensor is set on LOW. And you will investigate the effect of several variables on the magnetic field strength. Use a compass to identify the north pole of a cow magnet.

The object of this lab is to measure the magnitude of the earth's total magnetic field in Oxford, MS. The thing is anyone textlabs as well as other academic suppliers are frequently likewise substantial to look at instantly. The same le (magnetic eld) will be used for this part of the experiment. Place the Magnetic Field Sensor between the turns of the Slinky near its centre. The magnetic field lines follow the longitudinal path of the solenoid inside, so they must go in the opposite direction outside of the solenoid so that the lines can form a loop. - Determined 0= 2.3x10^-6 - Current incerease means Magnetic Field increases, vice versa. Magnetic fields are produced by electric currents; a simple segment of current-carrying wire will generate around it a circular magnetic field in accordance with the right hand rule. Laboratory #6 Magnetic Fields Objective This experiment has 2 parts: (1) you will map the magnetic elds around a bar magnet and a current-carrying coil, and (2) you will measure induced currents using a bar magnet and a galvinometer.
