Magnetic field in a loop---- B= B_1 +B_2 yo have to calculate 2 magnetic fields for a current negative(see Y axis) ( - ) plus current positive For a current I=0.2 and a=6cm Bz= 4.7125*10^(-6)
the problem of the sphere .. the magnetic field at the point p .. is all that I need to finish... we got the same values
@FLu.. No!!! We have the same values for all the test !! And I got it right (carring- ribbon !! Give me the B part of the last problem.. and i give this result..
