Using figure 317 determine the voltage induced if the magnet

Using figure 3.17, determine the voltage induced if the magnetic flux density is going into the page with a value of 0.8 [T]. The velocity of the wire moving from right to left is 10 m/s. The length of the wire is 1.8 m.

Solution

The induced voltage in the conductor of length l moving with velocity  v in the magnetic field of strength B is given by

voltage induced = B l v sin (theta)

V = 0.8*10*1.8*sin60

V = 12.47V
