Magnetism 2. Describe the pattern of an electromagnetic field around conductor carrying a constant current (L0 4.1) 3. A flux of 0.6Wb passes through a motor field pole with an area of 120 cm2. Calculate the flux density (L0 4.2) 6. Calculate the force on a conductor 40cm long, with a current of 100A, at right angles to a magnetic field of flux density 0.25T. Sketch a diagram to indicate the direction ofthe force relative to the conductor and the magnetic field (L0 4.2) 7. A force of SON acts on a current carrying conductor 80cm long at 30 to a magnetic field of flux density 0.50T. Calculate the current flowing (L0 4.2)
