Reference: OCR
The conductor's field interacts with the magnet's field to produce a force on the conductor, and this is exploited in loudspeakers and electric motors.
The force on a current carrying conductor in a magnetic field, produced by the interaction between a current and a magnetic field.
The effect that gives a force on each side of a coil carrying a current in a magnetic field, where the force is F = B I l.
A current-carrying conductor in a magnetic field can experience a force.
The force experienced by a current-carrying conductor when placed in a magnetic field, caused by the interaction between the magnetic field of the permanent magnet and the magnetic field produced by the current.
The force experienced by a current-carrying conductor when placed in a magnetic field.
