Faraday's Law of Electromagnetic Induction is-

The induced e.m.f (e volts) is equal to the negative rate of change of flux.

thank you

hehehe

Are u taking about Lenz's Law?
'An induced effect is always such as to oppose the cause that produced it'

But it doesn't matter whether is it positive or negative, as long as there is a change of flux, there will be a voltage induced to trigger the system.

it was Lenz who took Faradays law and introduced the word 'negative'
its still Faradays law imo
