Answer

From right to left.

Work Step by Step

Call the flux positive when magnetic field is pointing from left to right. As the magnet is pushed into the coil, the magnetic flux increases. To oppose this increase, the flux produced by the induced current must be negative, i.e., the induced field points to the left. By the right hand rule, current circles clockwise as seen from the right. The induced current in the resistor travels from right to left.
