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?

2. Relevant equations

Basically the most relevant equation is:

-(dɸ)/(dt)=Emf

3. The attempt at a solution

I'm not too sure how to attempt this problem. It would be greatly appreciated if someone could get me started.
