How strong is the magnetic field of a magnetic induction stirrer?

14 July 2021 1 3K Report

I am conducting a CO2 electrolysis experiment in aqueous medium, where I will be stirring the medium with a magnetic stirrer. I read in the paper linked below that a perpendicular magnetic field (to the surface of the electrode) of more than 1 T can improve bubble dispersion and thus solubility.

As I am stirring my medium with a magnetic stirrer, I was wondering whether such effect would apply to my system. But I am not sure about the strength and direction of the magnetic field generated by the magnetic induction stirrer. Is it ≥ 1 Tesla? And what is its direction?

Thanks

The discussed equipment is ordinary magnetic stirrer for liquids in which a magnetic piece rotates due to the magnetic field of another. The rotation of the latter is controlled electrically. For electrically operated small magnetic stirrer the field would be ~ 1kG but not ~1T.

Since the medium is field sensitive, it is desirable to measure the magnetic field by a guass-meter.
