Calculating Induced EMF in a Moving Loop of Wire with Uniform Magnetic Field

[mmm62892]

A square loop of wire measures 2.00 cm on each side. It is attached to a cart that is moving at a constant speed of 15.0 m/s into a uniform magnetic field of 56.0 T. (a) What is the induced emf after it has traveled 1.00 cm into the field? (b) What is the direction of the current, clockwise or counterclockwise? (c) If the resistance of the loop is 1.60 , what is the current in the loop?

What is this even asking and how does a cart have to do with emf? I'm so lost. :(

Have you learned about Faraday's Law? That would be the place to start. How is the velocity of the cart related to the change of the magnetic flux through the wire loop?
