Claim 0:
1. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
in a tubing positioned in a wellbore with an electrical submersible pump (ESP) and a magnetic field source mounted on the tubing, the magnetic field source positioned above the electrical submersible pump (ESP) and configured to generate a magnetic field to suspend iron-containing particles above a discharge of the electrical submersible pump (ESP):
activating the magnetic field, preventing an accumulation of the iron-containing particles onto components of the electrical submersible pump (ESP) during a powered-off state of the electrical submersible pump (ESP);
suspending, using the magnetic field source positioned above the electrical submersible pump (ESP), the iron-containing particles until the electrical submersible pump (ESP) resumes production to flow the iron-containing particles out of the wellbore; and
switching, by a controller, between powering the electrical submersible pump (ESP) and powering the magnetic field source, including powering a selected one of the electrical submersible pump (ESP) and the magnetic field source.
