Is this solution correct?

    I found this answer for an question of the Halliday's book but the units m².T.rad/s in the answer don't make sense with voltage. (sorry my poor english)
    And I cannt understand why they haven't expressed the current as a function of time.

    You have missed the T (tesla) in the permeability of free space.

    Okay, I notice that. Can you explain me why the current was not expressed as a function of time? I learned from the Faraday's formula that the flux's variation is basically a derivative wich involves the time.

    Because what they wrote is the amplitude of the emf.
    The amplitude is not time dependent. The formula includes the amplitude of the current, io.
