Question

if thmagnetic field is zero between loop 1 and loop 2 then find the current in loop 2​

Answer 1

Step-by-step explanation:

The magnetic field at the centre of a current carrying loop is

B= (u°/4π) * (2πI/r)

If loop has n turns, then

B= n * (u°/4π) * (2πI/r)

I is the current.

r is the radius.

So how it can be zero.

To fully understand this , just góogle it's derivation. It is quite easy to understand or just read any electrodynamics book.
