Physics for IGCSE & O level - Magnets And Currents (Section 1 - No. 45)
How can the direction of the magnetic field produced by a current-carrying coil be determined?
Using Ohm's law
Using the right-hand grip rule
Using Fleming's left-hand rule
It depends on the voltage
Објашњење
Fleming's left-hand rule describes the force on a wire in a magnetic field.
