A. A wire of length = 0.30 that runs north-south on a horizontal surface. There is acurrent of = 0.50 flowing north in the wire. The Earth's magnetic field atthis location has a magnitude of 0.50 and points north and 38 degrees down from thehorizontal, toward the ground. What is the size of the magneticforce on the wire due to the Earth's magnetic field?
B. Assume that a strong, uniform magnetic field of size0.55 pointing straight down is applied. What is the sizeof the magnetic force on the wire due to this applied magneticfield? Ignore the effect of the Earth's magnetic field.
C. Assume that the applied magnetic field of size 0.55 is rotated so that it points horizontally due south. Whatis the size of the magnetic force on the wire due to the appliedmagnetic field now?
