**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.I found this answer for an question of the Halliday's book but the unitsm².rad/sin the answer don't make sense with voltage. (sorry my poor english)

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

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.
