1. The problem statement, all variables and given/known data 4) The wing of an aircraft is 60m long and the aircraft is travelling at 250ms-1. The vertical component of the Earth’s magnetic field, which the wing is cutting, has the value of 4.3 X 10-5 T. Calculate: a. The Flux cut per second by the wing b. The induced emf set up across the wing 2. Relevant equations This s the equation given: E = N D Φ /Dt 3. The attempt at a solution Heres my attempt. My answers seem very wrong. Please help. Thanks. a. The Flux cut per second by the wing Magnetic field = 4.3 X 10-5 T Length of conductor = 60m Velocity = 250ms-1 E = Ф ÷ t E = (4.3 X 10-5 X 60) ÷ 250 = 103 X 10-7 T b. The induced emf set up across the wing E = BLV E = Induced EMF B =Flux density V = Velocity E = 4.3 X 10-5 X 60 X 250 =0.645.
