1) A uniform magnetic field has an x component of .43 T, a y component of .33 T, and a z component of .64 T. A wire 1m long and lying on the y-axis carries an 8.2A current in the positive direction. Draw a diagram and find the force on the charge.

2) What is the magnetic field at x=-1 and y=1 meter, if a wire lying on the x-axis carries 10A current in the positive direction. (Remember the magnetic field is a vector)
