I suggest you use the Lorentz force law to compute the force: F = L * I X B Here L is the length of the wire, I is the current through the wire, and B is the magnetic field. The operator "X" denotes cross product. | I X B | = | I | | B | sin?
So the magnitude of the force per unit length F = L * | I X B | / L = | I | | B | sin? We have 0.25 A and 0.0255 T. And sin (30) = 1/2.
So F = 0.25 * 0.0255 * 1/2 = 0.0032 N /m = 3.2e-3 N/m.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
