SHOW AND EXPLAIN ALL WORK. A wire of infinite length carries a current of 14.0 A in a uniform magnetic field of magnitude 0.45 T as indicated in Figure P.22. SHOW AND EXPLAIN ALL WORK. A wire of infinite length carries a current of 14.0 A in a uniform magnetic field of magnitude 0.45 T as indicated in Figure P.22. Find the force on a one meter length of the wire. N If the angle that the wire makes with the magnetic field is tripled what happens to the direction of the force? The direction is unchanged because the magnitude changes. The direction changes because the angle changes. The direction of the magnetic force is unchanged. The direction of the magnetic force is changed. Is the magnitude of the force triples? Explain you answer. The magnitude of the force triples because the sine is not a linear function of the angle. The magnitude of the force triples because the sine is a linear function of the angle. The magnitude of the force does not triple because the sine is not aExplanation / Answer
a) F = B*I*L*sin(20) = 2.155 N
b)
The direction of the magnetic force is unchanged.
F = B*I*L*sin(60) = 5.456 N
c) The magnitude of the force does not triple because the sine is not a linear function of the angle.
