the conductor (CL) can slide without friction on the vertical conductors which are made of insulated material. The mass of the conductor is m = 200gr the length of l = 1m the intensity of the gravitational field g = 10 m / s ^ 2, while the intensity of the homogeneous magnetic field B = 0.1T Calculate the current intensity and the direction in KA pipeline so that: a) the pipeline is rising at a constant speed, b) the pipeline rises with a constant acceleration a = 2 m / s ^ 2 c) the pipeline descends at a constant speed; d) the pipeline descends with constant acceleration a = 12 m / s. 2.
