The induced current in the coil:

I=I0e-bt, b > 0

According to Lenz's law, an induced current or emf always opposes the change in the magnetic field that causes it. 

The current is passing through a straight line creating a magnetic field around it.

The current through the straight line is proportional to the magnitude of the magnetic field.
