High magnetic field science is having an important impact in many disciplines, including medicine, chemistry, and condensed-matter physics. Two charged particles travel with some velocity, , through a uniform magnetic field, .As the charges pass through the magnetic field, each experiences a magnetic force, , due to their velocity, the direction and strength of the magnetic field and their charge, .Note that here the positive charge experiences an upward magnetic force and the negative charge experiences a downward force. The plot below was all that I had to work with. As the number of turns in the coil increases, the magnetic field strength will increase, in accordance with the equation B = NμoI / 2R. Again I was faced with the issue of superimposing my two vector fields. through a wire, a magnetic field is produced in the region around the wire. After some discussion with Professor Magnes, I decided I would take what I had, and make more complicated systems with it. 1. Ronaldo Degazon Friday 31/01/12 Physics Lab #17 Discussion: A magnetic field is the region or space around a magnet where the effects of the magnet can be experienced by any magnetic material. Initial hypothesis: Magnetic field strength will be proportional to the strength of the current running through a straight wire and inversely proportional to the distance from the wire. *When finished with your lab clean up your lab station. show that if identical current-carrying wires were aligned next to each other, their resulting magnetic field would resemble that of the field due to a plane of current as the distance between them decreases. With the current on and kept constant, the magnetic field strength was recorded at each circle on the polar graph paper by holding the sensor in line with the parallel lines on the sheet and so that the white dot on the sensor was on the left and at a 90o angle with the parallel lines pointing north. Faraday’s law states that a current will be induced in a conductor which is exposed to a changing magnetic field. The standard MKS unit for a magnetic field is Tesla. To examine the magnetic field associated with a bar magnet and construct the magnetic field lines.

Use the controls on the Magnetic Field Sensor (hardware) to set it to radial mode and 10× reading. As seen in my previous Final Data post, I was able to show that if identical current-carrying wires were aligned next to each other, their resulting magnetic field would resemble that of the field due to a plane of current as the distance between them decreases. A Tesla is 1N/amp*m. Magnetic fields can also be measured using the unit of gauss. The paper was placed on the plastic table of the apparatus and was aligned using a compass so that the parallel lines on the sheet were pointing north. Part I: Mapping Magnetic Fields Warning: These field maps must be done on the wooden lab benches; the metal tables interfere with the magnetic fields. The intensity of a magnetic field gets measured from three separate coil spacings, where each distance creates its own magnetic field. In this lab we will have a disk magnet (a dipole) suspended on a spring, which we will use to observe forces on dipoles due to different magnetic field configurations. In the last part of the experiment the magnetic field of a standard bar magnetic will be measured. 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.. You can create a stronger magnetic field by taking wire and forming it into a coil; the field is more concentrated in the center of the loop than outside the loop. The white dot of the sensor was aligned to be in the center of the cylindrical support with the white dot facing upward. Laboratory #6 Magnetic Fields Objective This experiment has 2 parts: (1) you will map the magnetic fields around a bar magnet and a current-carrying coil, and (2) you will measure induced currents using a bar magnet and a galvinometer.

Click on the back arrow of the web browser to return to the previous webpage. Discuss your drawing with a TA. Simply measure the magnetic field at various distances along the axis through the center of the magnet. Thus, increasing the current will result to an increase in magnetic field in that area which increases the magnetic force in return.

Perform a Linear Fit on your graph. PHYS 1493/1494/2699: Exp. 2. Possible sources of error include the difficulty of aligning the sensor perfectly along the radius of each circle, and it was also a challenge to get an accurate reading from the sensor as the readings kept jumping around. This value was recorded along with the respective radius. Perform a Linear Fit on your graph. Physics 15b Lab 3: Magnetic Fields and Induction In Chapter 5, Purcell uses relativity to derive the force acting between two moving charges, given the forces and charge densities in a stationary frame. The slope from this plot in comparison to the value of μoI / 2R, 6.7 x 10-5 T/turn, yielded a percent difference of only 2.6%. Theory states that the magnetic field produced by a long straight current-carrying wire decreases in strength as you get further from the wire. Magnetism also 2. For example, using your names, if the field from one wire was “bCart1” and from the other was “bCart2”, defining “fieldtotal = bCart1 + bCart2” and then using Vectorplot with fieldtotal as the argument should do the trick, I think. Calculate your value of μoI / 2π. Both were very difficult to find the magnetic field for at any given point and so I was at a loss for things to model.

Don't forget to rate and comment if you interest with this lab report sample. The value is 6.7 x 10-5 T/turn, which is very similar yet slightly large in value than the slope. According to Faraday’s Law a change of the magnetic flux through an area bounded by closed circuit induces a voltage that drives the flow of current around the circuit. The field then gets measured off- center to discover if the field remains uniform within a radial direction. In physics, a magnetic field is represented by the letter “B”. One gauss is equal to 1 x 10-4 Tesla. A wire carrying electric current I in a magnetic field B will be subject to a force Determine which side of the compass (either blue or silver) points along the magnetic field lines.
