1. The problem statement, all variables and given/known data A conducting slidewire system is set up as shown. The sliding wire has mass m and electrical resistance R and falls under gravity as shown. The fixed wire loop has zero resistance and lies perpendicular to a uniform magnetic field B shown pointing into the page. i) Use Faraday's Law to determine the maximum velocity of the slidewire. ii) How much power is dissipated at the peak velocity? 2. Relevant equations ɛ=-dФ/dt P=(I^2)R 3. The attempt at a solution I defined the area vector as pointing in the same direction as the magnetic field, so ɛ=-B(dA/dt) In time dt the slidewire moves a distance vdt, giving ɛ=-BLv where L is the width of the slidewire. I think I am simplifying the problem too much by simply rearranging for v in this equation and obtaining v=-ɛ/BL -should I differentiate in order to maximise v? I feel I am missing something by not including the given mass m. For the second part, overall current I=|ɛ|/R, so I=BLv/R P=I^2R=(BLv/R)^2/R P(dissipated)=(B^2L^2v^2)/R Thanks in advance for any help, much appreciated.
