Magnetic force/field problem

Turbo Math

1. The problem statement, all variables and given/known data

A wire extends horizontally from east to west. The mass of its meter is (0.18)g and it carries a current of (1)A. If the wire is in a magnetic filed (0.5)T that heads horizontally upwards, determine the least current that makes the magnetic force equal the wire weight

2. Relevant equations

F = BIl sin θ

3. The attempt at a solution

at first i dont understand what does "heads horizontally upwards" means so this is where i end up:

mg = BIl sin θ
(0.18E-3) x 10 = 0.5x1x1 sin θ
θ = sin^-1(1.8E-3/0.5)
θ = 0.2

I think horizontally upwards means perpendicular to the wire(direction of the current)

Turbo Math

You mean..

BIl = mg
0.5 I = 1.8E-3
I = 0.0036 A ?
