A wire carrying a current I enters regions ofuniform magneticfields. The upper region has a uniform magneticfield pointinginto the page, while the field points out of thepage in the lowerregion. The magnetic fields in both regions havea magnitudeB. The wire goes straight over a distance L, turnaround with asemi-circular path of radius R, and goes straightover a distanceL again before it exits the magnetic field region.The wire spansacross the two different regions evenly. Find thenet magneticforce on the wire. ® I®Rㅇ
