In Activity 13.7, how do we think the displacement of rod AB will be affected if
current in rod AB is increased;
When a current-carrying wire is placed in the magnetic field, it experiences a force,
this force is proportional to the length of wire, the strength of the magnetic field and the magnitude of the current passing through the wire.
And hence When current in rod AB is increased, it will experience a greater force and hence will be more displaced.
