1. The problem statement, all variables and given/known data How many times stronger is the force acting on the conductor at 90 degrees than it is at 30 degrees? 2. Relevant equations F = ILBsin(theta) 3. The attempt at a solution I would think the answer is two times as strong because sin90 = 1 and sin30 = 0.5. But the question is worth 5 marks so I think there must be something more to it..
