Learning outcomes
You should be able to:
■■ describe a magnetic field as a field of force and use field lines to represent a field
■■ determine the magnitude and direction of the force on a current-carrying conductor in a magnetic field
■■ define magnetic flux density and describe how it can be measured using a current balance
■■ explain the forces between current-carrying conductors
