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
