Answer:
The current flowing through the outer coils is
Explanation:
From the question we are told that
The number of turn of inner coil is
The radius of inner coil is
The current flowing through the inner coil is
The number of turn of outer coil is
The radius of outer coil is
For net magnetic field at the common center of the two coils to be zero the current flowing in the outer coil must be opposite to current flowing inner coil
The magnetic field due to inner coils is mathematically represented as
The magnetic field due to inner coils is mathematically represented as
Now for magnetic field at center to be zero
So
=>
