We present two-dimensional numerical magnetohydro-dynamic simulations of a cancelling magnetic feature and the associated coronal X-ray bright point. Coronal reconnection is found to produce significant Ohmic heating, and at the same time at least 90 to 95% of the magnetic flux of the converging bipole is cancelled. The last at most 5 to 10% is cancelled when reconnection occurs at the base. Reconnection happens in a time-dependent way in response to the driven footpoint motions.
