7. (20 pts) A conductive rod 0.5 m long moves with a speed of 3m/s perpendicular to a magnetic field. If the induced voltage generated between the ends of the rod is 0.8V, what is the strength of the magnetic field?

Step 1
We can use the formula for the induced voltage in a conductor moving perpendicular to a magnetic field: V = B * L * v where V is the induced voltage, B is the magnetic field strength, L is the length of the conductor, and v is the velocity of the conductor. We Show more…
