Answer:
The current is

Step-by-step explanation:
From the question we are told that
The first radius is

The number of turns is

The current rate is

The second radius is

The resistance is

Generally the magnetic flux induced in the solenoid is mathematically represented as

Where is the magnetic field mathematically represented as

Where
is the permeability of free space with a value of

and A is the area mathematically represented as

So

Substituting values


The induced emf is mathematically represented as


substituting values


From Ohm law
