Write an algebraic expression for the magnetic field B at a distance from a long straight wire carrying current 2. B = mu_0/(2*Pi)*(i/r) Ho Your last answer was interpreted as follows: • (-) 2-T The variables found in your answer were: [o,r] In this simulation you can change the strength and direction of the current and you will be able to measure the the location of the magnetic field probe relative to the cen of the wire. • Click Begin on the simulation below. • Click Grid (top middle). • Click Current (bottom right), select any value and record it here: ; = 2.4 Your last answer was interpreted as follows: 2.4 • Set Direction (bottom middle) so that Conventional Current is to the right. 10 1 2 3 4 5 6 7 8 9 OCTIC FIELD + Magnetic Field from a Wire Lab 8 7 6 5 3 2 2d Field Distances (cm) A. Location of Field Sensor Field Strength Direction (Electron Flow) Current Question In reality, the above experiment (calculating by measuring the magnetic field at certain positions from a single wire) is very impractical / difficult to accomplish with a high degree of accuracy in the real world. Suggest and justify at least ONE reason why this SPECIFIC experiment is difficult to conduct well in reality. You can use more than one reason if you like. Suggest and justify a DIFFERENT experiment you could use to measure that would be better. A B I III 2?
