C h a p t e r 4 | 1008. Find the speed that a conductor <strong>of</strong> length 120mm must be moved at right angles to amagnetic field <strong>of</strong> flux density 0.6 T to induce in it an emf <strong>of</strong> 1.8 V.(25m/s)9. A 25 cm long conductor moves at a uniform speed <strong>of</strong> 8 m/s through a uniform magneticfield <strong>of</strong> flux density 1.2T. Determine the current flowing in the conductor when (i) itsends are open-circuited (ii) its ends are connected to a load <strong>of</strong> 15 ohms resistance.(0, 0.16A)10. A conductor <strong>of</strong> length 0.5 m situated in and at right angles to a uniform magnetic field<strong>of</strong> flux density 1 wb/m 2 moves with a velocity <strong>of</strong> 40 m/s. Calculate the emf induced inthe conductor. What will be the emf induced if the conductor moves at an angle 60º tothe field.(20V, 17.32V)<strong>Basic</strong> <strong>Principles</strong> <strong>of</strong> <strong>Electromagnetism</strong>
