Point out the direction of the current, Physics

Assignment Help:

Point out the direction of the current if any induced to flow in the coil by the changing magnetic field. (Depicted is a view of the coil from the side. Toward the top of the display in the diagram is upward.)

Answer:

The key to putting Lenz's Law is figuring out what change in the magnetic field through the coil is occurring and establishing what direction a new magnetic field would have to be in to fight that change. At this time we have an up-through-the-coil magnetic field which is increasing. To fight that raise we need a down-through-the-coil magnetic field. Therefore Bpin the magnetic field produced by the induced current, must be down-through-the-coil.

Now we have to enquire our self in what direction must the current flow around in the coil in order to produce a downward-through-the-coil directed magnetic field. The magnetic field is the direct thing in this problem so we point our right thumb in the down-through-the-coil direction and note that our fingers then curl around in the clockwise as viewed from above direction.
