A circuit contains two long straight wires laid out on a horizontal surface and an ideal source of emf ε. A straight wire of length l is symmetrically placed on the wires as shown and held in place. The resistance of a unit length of all wires is λ. The mass of the wire of length l is m. Angle θ is given. The circuit is placed in the uniform magnetic field B directed into the page. Neglecting friction and the induced emf, find the maximum speed of the wire after it is released.

We received many solutions to our February Challenge, A Heated Exchange, including quite a few from students (a welcome development!). We are pleased to recognize the following contributors:
