Answer:
The direction of induced emf is revered and hence the direction of the induced current.
Explanation:
If the polarity of the magnet is reversed, the direction if the field lines through the solenoid is also reversed, which according to Faraday's law means
[tex]\varepsilon =N\dfrac{d\Phi}{dt} \rightarrow -N\dfrac{d\Phi}{dt}[/tex]
in other words, the direction of the magnetic flux is revered, and therefore, the direction of the induced emf is also revered.
Furthermore, according to Ohm's law
[tex]I = \dfrac{\varepsilon}{R}[/tex]
which tells us that if the induced emf changes sign (is reversed)
[tex]I = -\dfrac{\varepsilon}{R}[/tex]
the direction of the induced current is also reversed.
