Fleming's Left-Hand Rule | GCSE Physics Practice
Use your left hand to predict the direction of the force acting on a current-carrying wire in a magnetic field.
Which finger represents the magnetic field?
What is Fleming's Left-Hand Rule | Practice?
"A simple rule used to find the direction of the force on a current-carrying wire in a magnetic field."
Magnetic field lines always point from ____.
Why are step-up transformers used in the National Grid?
Increasing the current through a solenoid will ____ its magnetic field.
What happens to an electromagnet when the current is turned off?
Hand Prediction
First Finger: Direction of the Magnetic Field (N to S).
Second Finger: Direction of the Current (+ to -).
Thumb: Direction of the Force (Motion).
The three must be at right angles to each other.
Hand Switch Warning: Use your LEFT hand for the Motor Effect. Using the right hand will give you the exact opposite answer!
