Consider two single turn coils labeled 1 and 2 that are positioned close to each other. The switch S has been open for a long time. If the switch is now closed and the current through coil 1 is in the direction shown and increasing, which of the following statements is true?
a.The current in coil 2 will be in the same direction as in coil 1.
b.The current in coil 2 will be in the opposite direction as in coil 1.
c. There will be no current in coil 2.
d.The direction of the current in coil 2 will depend on the size of the resistance R.
e. The direction of the current in coil 2 will depend on whether the area of coil 2 is larger or smaller than that of coil 1.

the current in coil 2 will generate a magnetic field that opposes the magnetic field from coil 1. Use your right hand rules to figure out the direction of the current.
