Question
III. Graphing relationships Using the Electromagnet simulation. Click on "Show Field Meter", Set the battery voltage to 10 V where the positive in on the right of the battery and the number of loops to 1. Along the axis of the coil and at the center of each compass needle starting 5 to the left of the coil, record the value of magnetic field B. Move one compass needle to the right and record the value of B until to the 5 compass to the right of the coil. Set the number of loops to 4 and repeat until you've complete the table below NOTE: Be sure to take all of your values along the axis of the coil. You'll know you've on the axis because the y component of the magnetic field is zero along the axis. Magnetic field strength (Gauss) Compass position r (arbitrary units) N=1 1.39 -4 .20 a 36 SS H AS 00 -3 L200 23 200 oo 900 38 312 24 9 00 a. a Design an experiment to investigate the relationship between the magnetic field strength B and the number of coils N. Collect data in a table. 3.1Explanation / Answer
3.1 design of an experiment to evaluate the relationship between magnetic field strneght and number of turns of coil
a. keep the compass at a fixed location, prefereably near the axis of the solenoid
b. click on the "show field meter" option
c. change the number of loops of the electromagnetic keeping every thing else fixed and note the readings
number of loops magnetic field
1 0.76
2 1.51
3 2.27
4 3.02
plot this on a graph
the plot follows a straight line
which means that the number of loops are directly proportional to the magnetic field created by the solenoid
