# Current Induced in Straight Conductor in Magnetic Field?

I came across this question while studying for a Physics test, with the corresponding answers posted below it.  But isn't the direction of the induced current as a consequence of Lenz's law such that the new magnetic field it induces opposes the original magnetic field, not that it must cause an opposition of motion or force (although this is sometimes a logical consequence)? I have only understood Lenz's law in the context of loops of wire such that an electromagnet (in the style of a solenoid) is created and thus finding the direction of the current is easy. Because by this logic wouldn't the direction of current on each side of a loop be the same, meaning the current can't flow through the loop?

Any help is greatly appreciated.

The force felt by this current due to the external field is in the direction of $$\vec{I}\times\vec{B}$$. By the right-hand rule again, if the current is flowing up and the external magnetic field is into the page, the force is to the left.
