A short straight section of the coil in a loudspeaker lies in a magnetic field that points from left to right across the page. The current in this section is perpendicular to the page, and the section is pushed up the page.
The magnet is then refitted the other way round, which reverses the field. The current is not changed.
In which direction is the conventional current in the section, and in which direction is the section pushed after the magnet is refitted?
