Mathematics

Step-by-step explanation:

Given that,

The length of a wire, L = 48 m

Current in the wire, I = 18 A (west to east)

The magnetic field in the wire, B = 8.3\times 10^4\ T (towards south)

The magnetic force acting on the wire is given by :

F=I(L\times B)\\\\F=48\cdot18\cdot8.3\cdot10^{-4}\ N\\\\F=0.71\ N

Using right hand rule, the direction of magnetic force is upwards.
