Consider the following statement for a circular conductor moving in and out of the magnetic field:

1. The polarity of induced motional EMF is such that it supports the change in magnetic flux responsible for its production.
2. Magnetic flux is independent of the area of the circular conductor.
3. If the coil is cut somewhere and then moved in and out of the magnetic field, EMF will be generated.
4. The basic cause of induced emf is the change in magnetic flux.

Which of the following statements are correct
