Assume we give square wave of 50 hz supply to txmr .
from 0 to postive maximum and then it will remain in maximum
value and same for negative axis also . since the rate of
rise from 0 to max + value / _value occurs at one instant of
time and not gradual . there will be no emf at secondary
terminals .

E = 4.44f*flux*turns*sinwt ( w =2pi* freq)- instantaneous
