So, if we want to find the component of a vector A in the direction of another vector B, we can use the scalar product, but we must divide by the magnitude of B (which we represent as B), because this magnitude is not relevant. (Thus, the component of a vector A in the direction of B is the scalar product of A and b, following our current notation.) The diagram below illustrates this result.

To find the direction of the induced emf, one can use Lenz's law: The induced current's magnetic field opposes the change in the magnetic flux that induced the current. For example, if the magnetic flux through a loop increases, the induced magnetic field is directed opposite to the "parent" magnetic field, thus countering the increase in flux.

The magnitude of the forces with which the wires interact with each other does not depend on the direction of the current in the wires and is, in both cases, equal to 0.4 mN. If the direction of the current in the wires is congruent, they attract each other, and in case of the opposite directions of the currents, wires repel each other.

The magnitude of the current in the wire is: The magnitude of the electric current in the wire is 0.100A. The direction of the electric current can be determined using the "right hand rule".
