Question

1) The magentic flux through a closed surface surrounding only the south pole of a bar magnet is ALWAYS greater than zero.

2) The magnetic flux through a fixed circular loop is maximum if the magnetic feild is oriented perpendicular to the plane of the loop.

3) An EMF is induced in a loop of conducting wire if the magnetic flux through the loop changes with time

4) If a bar magnet is falling toward the center of a loop of conducting wire, with the north pole oriented downward, the induced current in the loop is clockwise is viewed from the side of the loop.

5) If a horizontal metal bar oriented east-west drops straight down in a location where Earth's magnetic field is due north, the west end of the bar will be POSITIVELY charged.

6) If an RL circuit, the inductor behaves like a short-circuit as the current reaches its maximum value.
