Question

At this workatation you will find a eil slong with per supply and a Labquest Supply can be varied but the posnm of the magnetic feld probe has been A ent system with magnetic field peobe, The erent seting om the set and should not t be moved during this exercise. Your task is to determine the gnitude of s coil. Don1 use the events with emtry option here, only ohserve and record in the magnetic feld st the center of the eol as a funetion of eurrent in the table below the magnetic field valoe as R sppears om the Labguest screen. the power supply to achieve the actual valoes reasonally close to the nominal The nominal (approximate) current valoes are specified here; youa should adjast values. Record your data here. Nominal Current (amp) Actual Current Magnetic Field (mT) DIGMTTD.DDoo 1. o 2. 0.25 3. 0.50 50 ,74 4. 0.75 208/0.b6173T 3.51510.003suST 5 1.00 I. 06 6. 1.25 You are finished collecting dats, You can move to the nest work area Plot Magnetic Field in T (not mT) vs Actual Current in Amperes by hand using the provided graph paper. Determine the best linear fit for your data. Write down the modeling results, i.e. the equation for B() and identifying slope and intercept, below. Be sure to include proper units. Include your graph with the exam. Equation forB (I) from linear regression: ६वट 4.9& 1a-4 Slope Results: Intercept Based on your data, determine the number of turns per unit length, n. O.D08548 28393 n =

Answer 1

Here the unit of slope will be T/A and unit of intercept ist ? As we know that B = Mon I or n=/ 3 x I or na slopex I or n= slope - slope check your value of slope once again and then substitute inequate I ne slope पा
