A thin copper wire is bent to the shape of a rectangular loop and is suspended using a lab stand (as you saw in the lab demonstration). A vertical magnetic field is applied across the bottom horizontal section of the wire. Length of the bottom horizontal section of the wire is 15.0 cm and the two vertical sides are 30cm each. Diameter of the wire is 0.2mm. When a DC voltage of 1.5V is applied to the wire loop, it tilts 12 degrees from the vertical. Calculate the magnitude of the applied magnetic field. Show your work. (mass of any part of the wire is non-negligible)
