# Constant, Non-constant, Functional Current

Electricity and Magnetism Level 3

A straight wire with a resistance of $$\rho$$ per unit length is bent to form an angle $$2\alpha$$. A rod of the same wire material perpendicular to the angle bisector of the angle $$2\alpha$$ forms a closed triangular loop. The loop is placed in a uniform magnetic field of induction $$B$$ and is moved with a constant velocity $$v$$ as shown in the figure above.

The current induced in the loop is ?
