Q 14 An electron moves around the nucleus in a hydrogen atom of
radius 0 51 Å, with a velocity of 2 × 10 5 m/s
Calculate the following:
(a) the equivalent current due to orbital motion of electron,
(b) the magnetic field produced at the centre of the nucleus,
and
(c) the magnetic moment associated with the electron

Dear Student,
 if the flow of charge per unit time 
find the time taken by the electron to do one revolution
i=1 6*10-19*2*1052π*0
51*10-10=10-4 Amagnetic field B=μ0i2r=4π*10-7*10-42*0
51*10-10=1
232 Tmagnetic moment=iA=10-4πr2=10-4π0
51*10-102=8 17*10-25A-m2Regards
