1.A wire carrying a current of 10A and 2 meters in length is placed in a field of flux density 0.15T. What is the force on the wire if it is placed (a) at right angles to the field, (b) at 45° to the field, (c) along the field? 2. A long straight conductor x carrying a current of 2A is placed parallel to a short conductor y of length 0.05 m carrying a current of 3A. The two conductors are 0.10m apart. Calculate (i) the magnetic field B due to x at y, (ii) the approximate force on y. 3)A narrow coil of 10 turns and area 4x102 m2 was placed in a uniform magnetic field B of 102T calculate the average induced emf in the coil if it is removed completely from the field in 0.5s. b) if the same coil is rotated about an axis through its middle so that it turns 60° in 0.2s in the field B, calculate the average induced emf.
