Physics for IGCSE & O level - Magnets And Currents (Section 10 - No. 10)
In what direction does the turning force act on a coil?
Opposite to current.
Perpendicular to the magnetic field and current.
Along the coil
Parallel to the current
توضیح
The turning force is a result of the interaction between the current and the magnetic field, and therefore is at a right angle to both of them.
