Question
Consider the rectangular loop pictured in Figure 1 below. The loop is traveling with a constant velocity and enters the uniform magnetic eld at time t = 0. Assume that all parameters shown in the figure are known. Use any of the above equations to solve.
A) Calculation: Determine the maximum induced emf in the loop? Please show all your work.
B) Calculation: Assume that the loop has a resistance R. What is the maximum current that will run through the
loop? Please show all your work.
C) Conceptual: What direction does current run through the loop (clockwise, counter-clockwise, or none)? Please explain.
These are the fundamental equations from the modules we have covered so far. You may use other physics equations from your book, but you must reference where they come from coulomb's law (magnitude of electric force) magnitude of electric field from point charge force on point charge kinematics equations v(t)+at electric potential due to a point charge electric potential difference between points in uniform field (remember that 8 is displacement in the direction of the field) electric potential energy of a point charge capacitor equation effective capacitance (series) effective capacitance (parallel) capacitor potential energy parallel plate capacitor capacitance current current in beam or through wire cylinder resistance temperature dependence of resistivity Ohm's Law effective resistance (series) effective resistance (parallel) resistor dissipated power emf generated power discharging capacitor magnetic force on charge magnetic force on current-carrying wire magnetic torque on current-carrying loop circular motion in magnetic field magnetic field from long straight wire magnetic field at center of circular loop magnetic field inside a solenoid magnetic flux C C1+ C2...

A) inducd emf e = B*L*v =
B) maximum current is Imax = e/R = (B*L*V)/R
C) according to Lenz's law ,to oppose the increase in magnetic flux,the induced current must be in counter clock wise direction
