Compute the value of magnetic flux density in air at a point 5cm from a long straight wire carrying a current of 15A.

1. Determine the induced voltage in a conductor 60 cm long moving in the magnetic field at a velocity of 8000 ft per minute. If the flux density is 0.18 Wb/meter-square and the angle between the flux and the conductor is 60 degrees.

The magnetic flux density measured 1 meter from a current carrying wire is 0.000333 Tesla. The current in the wire is 10A. The magnetic permeability of the medium surrounding the wire is most nearly: a) 1.09 x 10-4H.m b) 6.28 x 10-4H·m-¹ 1 c) 2.09 x 10-4H.m-1 d) 5.08 x 10-4H∙m¯¹
