Answer 1

The statement is correct.

Answer 2

The statement "when a magnetic flux linked with conductor changes an emf is induced in it" is an accurate description of Faraday's Law of Electromagnetic Induction. According to this fundamental law, an electromotive force (emf) is induced in a conductor or a coil whenever the magnetic flux ($\Phi_B$) passing through it changes over time. The magnitude of the induced emf ($\mathcal{E}$) is proportional to the rate of change of magnetic flux, expressed by the formula:

$\mathcal{E} = - \frac{d\Phi_B}{dt}$

The negative sign in the formula indicates the direction of the induced emf, which, according to Lenz's Law, opposes the change in magnetic flux that produces it.
