What is the potential difference used in medical imaging techniques like MRI?

“When you connect two conductors by a wire and charge moves between them as to make difference in potential of the system zero what is the charge of the wire? Potential difference is the difference in potential energy for each electron. Potential difference has the symbol V, and the unit of Volts.
