Quick Answer:The Fleming’s Left Hand Rule Apparatus demonstrates the force on a current-carrying conductor placed in a magnetic field, the motor principle, with 4 mm safety sockets for connecting a DC power supply.
Last updated: 18 October 2026
Key Features
Shows the motor effect predicted by Fleming’s left-hand rule.
Permanent magnet provides the magnetic field.
Conductor moves visibly when current flows through it.
4 mm safety sockets for a DC power supply.
Weighted, non-magnetic base for a stable set-up.

How It Is Used
A DC supply is connected to the sockets so current passes through the conductor lying in the magnet’s field. The conductor is pushed sideways, and reversing the current reverses the direction of movement, letting students relate the directions of field, current and force as the left-hand rule describes.
Frequently Asked Questions
How is the Fleming’s Left Hand Rule Apparatus powered?
It connects to an external DC power supply through 4 mm safety sockets on the apparatus.
