1. The problem statement, all variables and given/known data A high-voltage power line carries a current of 106 A at a location where the Earth's magnetic field has a magnitude of 57.1 µT and points north, 71.9° below the horizontal. Calculate the magnitude of the magnetic force exerted on a 251 m length of wire if the current in the wire flows horizontally east. 2. Relevant equations F=I*L*B*sin(theta) (magnitudes) 3. The attempt at a solution 106*251*57.1*10-6*sin(18.1)= 0.47198 N However, the system says I'm wrong. Is the computer at fault here?
