Product description
A metal jumper with mass m = 50 g rests on horizontal conductive rods. The coefficient of friction between the rods and the jumper is µ = 0.15. The rods are connected to a resistor with a resistance of R = 5 Ohms. The system is in a magnetic field, the magnetic induction of which is directed vertically upward, and its module changes with time according to the law B = At, where A = 5 T/s. Determine the moment in time at which the jumper begins to move along the rod. Geometric dimensions: l = 1 m, h = 0.3 m. Neglect the resistance of the jumper and conductive rods.
