orque due to the magnetic fieldτmag​=μ​×B
Let the wire loop be in xy plane.
Letμ​=μk^
B=B0​(−i^)
∴τ=μk^×B(−i^)=μB(−j^​)=IAB0​(−j^​)
Torque due to the weight mg isτmg​=mgR where R is the radius of the circle.
If the loop does not tilt both the torques need to balance each other.
∴IAB0​=mgR
⇒I=AB0​mgR​=πR2B0​mgR​=πRB0​mg​
