As performed in the real lab:
A horse shoe magnet, a small aluminium rod, an ammeter, two wooden stands, two connecting wires, a battery, a plug key.
- Suspend the aluminium rod horizontally from the stand using clean connecting wires.
- Place the horse-shoe magnet in such a way that the rod lies in between both the poles such that south pole is vertically above and north pole is vertically below the rod.
- Connect the rod in series to the battery, key and the rheostat.
- Now switch on the current and observe the displacement of the rod.
- Reverse the direction of the current and observe the change in the displacement of the rod.
As performed in the simulator:
- Click on "Switch" to start/stop the flow of current through the circuit.
- Observe and note the change in the position of the aluminum rod as the current flows through the circuit.
- To reverse the direction of the current switch off the circuit, then click on the wire.
- Repeat the procedure.
Observation & Inference:
On passing current through a straight conductor (aluminium rod) kept in a magnetic field, the conductor gets displaced upward or downward.
- The direction of displacement of the conductor rod changes with the change in the direction of current through it.
- The displacement of aluminium rod is in accordance with Fleming’s left-hand rule.
