AH Exp – Electrical Phenomena 01 – Force on a conductor in a magnetic field and current in the conductor

Aim – To investigate the relationship between the force exerted on a conductor in a magnetic field, and the current in the magnetic field.

Instructions

▪ Note the reading on the balance. This is the mass of the magnets and yoke.
▪ Click on the red buttoned switch to close the contacts of the switch.

Clicking on the right side of the potentiometer reduces its resistance. Clicking on the left side to increases its resistance.

▪ By changing the resistance of the potentiometer, pass a current through the wire. Note the reading on the balance.
▪ Hence determine the force on the conductor due to the magnetic field.
▪ Repeat for different values of current.
▪ Plot a graph to show the relationship between the force on the conductor and the current in the conductor.
