what is the module of a magnetic field where a wire is 0.02m and circulates a current 7A?

Im thinking the formula is Fb= IxLxB, but there is no force mentioned, so can't substitute that for mass either, not sure

Wouldn't B vary by distance from the wire segment? B is dependent to current, the length of the wire, and distance from the wire.
