Solution Summary

The solution shows all mathematical steps and gives explanation for each step in a very clear manner.

Solution Preview

This problem can be solved using Faraday's law of electromagnetic induction. The induced emf is called motional emf.

Motional emf is largest when the direction of motion of the bumper (a metal rod) is perpendicular to the magnetic field.

    There will be: (a) a negative voltage induced across its ends (b) a positive voltage induced across its ends (c) no voltage induced across its ends (d) a time-varying voltage induced across it ends (e) none of these. Explain your choice. 2.

  • Magnetic field and Voltage induced

    If a current I flows through the wire, what is the voltage induced in the loop when the coil is a distance b from the wire in terms of L, I, v, a and b?

  • Elctromagnetic induction and the Lorentz force

    Simplifying: b/x - b/(x+a) = ba/[x(x+a)] then gives the desired result. When the loop moves in the direction of the wire there is no induction voltage. The reason is that the flux remains constant.

  • Physics: Magnetic & Induction

    A bar of 1 m length aligned in y direction moves in +x direction at 10 m/s, in space where B = 1 T pointing in the - z direction. Calculate the motional EMF. 4f2.

  • Voltage difference of a space station module shaped like a cylinder


    Because, the emf induced in a conductor is given by:
    e = B*v*l
    here, B,v and l must have the perpendicular components to one another. When all three physical quantities are perpendicular to one another the induced emf be maximum.
