A straight, rigid conductor of length 8.0 cm within a high-speed optical scanner's electromagnetic actuator is aligned perfectly at right angles to a uniform magnetic field between two magnetic poles, as shown in the diagram.

Electromagnetic actuator schematic

During a calibration sweep, the system records the following data:

  • current in the conductor = 4.5 A
  • magnetic force acting on the conductor = 0.162 N

Calculate the magnetic flux density of the uniform magnetic field.
