To perform the activity you need to follow the following steps:
Get a battery, two magnets of different sizes and magnetic intensities, an aluminium rod, connecting wires, stand,
Now arrange the above mentioned articles as shown above.
When the arrangement has been made keep the rod still in air and switch on the current.
Observation: Nothing happens.
Now bring the magnet with lower magnetic intensity closer to the aluminium rod.
Observation: The rod deflects. Closely observe the velocity of the rod.
Inference: A current carrying conductor in magnetic field experiences force.
Now steady the rod and bring the both the magnets closer together (to ensure that the magnetic field is greater than in the previous case).
Observation: The rod moves towards the magnet only this time it is faster as it was earlier.
Inference : The above is possible only and only if the force acting on the rod is more than in the previous case. Because since the body will be starting with zero velocity it will move faster only if its acceleration is more and since acceleration more the force acting on it is more. Thus, force acting on a current carrying conductor placed in a magnetic field increases with the increase in the field strength.
Consider the diagram below..
