Urinary tract infections (UTIs) drive over eight million people to seek medical attention every year. Almost all — as many as 90% — of those infections are caused by Escherichia coli.

The geometry means the two magnets are automatically at the ends of the generated magnetic field, where the field is divergent, so a force is exerted on the magnets.
