Two high-current transmission lines carry currents of 45 A and 78 A in the same direction and are suspended parallel to each other 28 cm apart. If the vertical posts supporting these wires divide the lines into straight 16 m segments, what magnetic force does each segment exert on the other? N. Exponential format with 2 SF. QUESTION 14 An induced emf will occur if A. the strength of the magnetic field changed. B. the coil's area is changed. C. the angle at which the magnetic field and the coil's area meet is changed. D. all of the above.
