Answer 4_10_5

The coil in question 4 is now turned so that it makes an angle of 60 o with the magnetic field lines.  What is the change in flux linkage?                                                                            

 

Original flux linkage = 0.05 Wb (P)

 

New flux linkage =  200 ´ 2.5 ´ 10-3 T ´ 0.1 m2  ´ sin 60 (P)

 

= 0.05 Wb ´ 0.866 = 0.0433 Wb (P)

 

DF = 0.0433  Wb    0.05  Wb = - 6.7 ´ 10-3 Wb (PP)
