Abstract
The electric properties in YBCO superconductor was studied. In the measurement of current-voltage characteristics, a voltage across the superconducting sample was observed on applying an external magnetic field. The voltage increases with increase in applied magnetic flux, but it becomes constant at about $10^{-2}T$. The voltage continues to appear the removal of the magnetic field. The appearance of the voltage is ascribed to the trapping of magnetic flux. Depending on the direction of applied magnetic flux less than $2.5{\times}10^{-5}T$, the voltage in the magnetized sample increases or decreases.
