Question

Part II. Electomagnet (flat coil radius is larger than the length) Use: click the tab on top for electromagnet Unclick the show compass click show field meter Start with 1 loop and the meter 50 cm from the loop. Set the battery for 1 volt, measure the magnetic field. Increase the voltage by lv, measure the magnetic field, record your values in the table. Plot the B vs. the voltage. Note the resistance is constant so increase voltage produces an increase current. Does B increase linearly with current? The radius is 10 cm. z = 5 cm, N = 1, what is the value of the current?

Answer 1

a arcular B (MT) 2 Mo I a² 40 Ca2+x2) 3/2 10 7 1.98 109 ()) Here only and B is said to Jabulate but additionally I Jabulated current I with them also to show B-1 Yelationship. The freld meter fired at a distance and it is assumed to be the distance between Coil and meter is 5o con. There are no inbuild ruler to maintain and measure distance. We know that for Current Carrymy loop, Mo na a = dolm ; a=0.5m Substitating the values and rearranging we get I = 2.11 x 10tx B A Voltage I = 2.11 X 10 XB Co CA 0:28 x 10-4 590.8 2 0 57 xloh 1202.7 3 0.85 x 10h 1793.5 1.13 xloh 2384.3 5 1.41X loh 2975.1 1.70 1-70 x 164 3587 7 1.98 41778 Table-II B B (T) 0.28 0.57 0.85 1.13 4 ihl 6 2.26 8 १ 2.26 Xloh 2768.6 2:55 538 0.5 10 2.55x109 2.83X105 2.83 59713

3) Table - Part 2 v=lov Constant X, a= constant Change number of loops and record B number of loops B 1 0.27 2 0.55 3 0-82 r 1.09 (wecam Change up to 42 so from Table I part I as V and I hcreases B increases (mearly from Jable II part II, B increases almost I mearly with number of Jams.
