Aconducting rod (length = 2.0 m) spins at a constant rate of 2.0 revolutions per second about an axis that is perpendicular to the rod and through its center. a uniform magnetic field (magnitude = 8.0 mt) is directed perpendicularly to the plane of rotation. what is the magnitude of the potential difference between the center of the rod and either of its ends?

0.050V

Explanation:

To solve this problem it is necessary to use the concepts related to the potential between two objects that have a magnetic field, this concept is represented in the equation.

Where,

v= tangencial velocity

B = Magnetic Field

We know for definition that,

Where,

L = length

Angular velocity

We can replace this values in our first equation then,

Integrating we have,

Replacing the values,

Therefore the potential difference between the  center of the rod and the other rod is 0.050V
