Electricity has taken a central role in modern society. This is due largely to the ease in which electricity can be generated, transmitted, and converted into other useful forms of energy.
One of the fundamental interactions which enables this is called the motor effect. When a current-carrying conductor is placed in a magnetic field, it experiences a force.
These slides outline the motor effect, the right hand palm rule (slap rule) as well providing some brief comments on the Board of Studies context.
