Lenz's Law Problems

Problem 1
In figure 1, does the loop of wire have a clockwise current, a counter-clockwise current, or no current if:

• The magnetic field strength is increasing?
• The magnetic field strength is constant?
• The magnetic field strength is decreasing?

 

Problem 2
In figure 2, does the lower loop of wire have a clockwise current, a counter-clockwise current or no current:

• Before the switch is closed?
• Immediately after the switch is closed?
• Long after the switch is closed?
• Immediately after the switch is opened again?

 

Problem 3
In figure 3, does the current through the meter flow right to left, left to right, or is there no current if:

• If the magnet is pushed into the coil as shown?
• If the magnet is held at rest as shown?
• If the magnet is pulled out of the coil?
