||This EMF is like the EMF of a cell. It is available to drive a current around a circuit. If we attach a load to the wire, then a current will flow. We call this an induced current. However, as soon as we take a current from the wire, the wire will feel a force (a wire carrying a current in a magnetic field feels a force).
We can use Fleming's Left Hand Motor Rule to work out the direction of the force. In this case it is to the left.
In other words, the force will push against the motion of the wire. The wire will slow down. If we want to keep it moving, we'll have to push it.
If we take a bigger current from the wire, we'll have to push it harder. The bigger the current we get from the induced EMF, the more work we have to put in.
This makes sense: we don't get something for nothing. When we take a bigger current, we are getting the induced EMF to do more electrical work for us. Therefore, we have to put in more mechanical work. This is the conservation of energy.
