The 2900-turn coil in a dc motor has an area per turn of 2.1 × 10-2 m2. the design for the motor specifies that the magnitude of the maximum torque is 8.2 n·m when the coil is placed in a 0.23-t magnetic field. what is the current in the coil?

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
