A doubly ionized molecule (i.e., a molecule lacking two electrons) moving in a magnetic field experiences a magnetic force of 5.23 x 10-16 N as it moves at 317 m/s at 69.5 to the direction of the field. Find the magnitude of the magnetic field. TA flat, 187 turn current-carrying loop is immersed in a uniform magnetic field. The area of the loop is 5.27 x 10-4 m, and the angle between its magnetic dipole moment and the field is 49.7. Find the strength B of the magnetic field that causes a torque of 1.43 x 10- N.m to act on the loop when a current of 0.00241 A flows in it. B = TWhen operated on a household 110.0 V line, typical hair dryers draw about 1450 W of power. The current can be modeled as a long, straight wire in the handle. During use, the current is about 2.75 cm from the user's hand. What is the current in the hair dryer? A What is the resistance of the hair dryer? What magnetic field does the hair dryer produce at the user's hand? The permeability of free space is Mo = 4x X 10-7 N/A2. T
