Homework Statement
A circular wire loop of radius r= 19 cm is immersed in a uniform magnetic field B= 0.670 T with its plane normal to the direction of the field.
If the field magnitude then decreases at a constant rate of −1.2×10−2 , at what rate should increase so that the induced emf within the loop is zero?
Homework Equations
Basically the most relevant equation is:
-(dɸ)/(dt)=Emf
