Which of the following statements are equivalent to saying that the flux of the magnetic field through any closed surface is always zero? (select all that apply) there are no magnetic monopoles in nature magnetism obeys Faraday's Law magnetic field lines are always closed loops magnetic field lines can never cross the induced emf always opposes the change in the flux magnetic field lines are basically the same as electric field lines

Answer #1

answer is : there are no magnetic monopoles in nature. magnetic field lines are always closed loops

By Gauss law for magnetic field, the flux through closed surface is directly proportional to the number of magnetic monopoles enclosed by that surface. However, magnetic monopoles do not exist because of Magnetic field-lines form closed loops which never begin or end. so magnetic flux through closed surface is zero.

    Learning Goal: To understand the terms in Faraday's law and to be able to identify the magnitude and direction of induced emf. Faraday's law states that induced emf is directly proportional to the time rate of change of magnetic flux. Mathematically, it can be written as E=???B?t, where E is the emf induced in a closed loop, and ??B?t is the rate of change of the magnetic flux through a surface bounded by the loop. For uniform magnetic fields the...
