What Is the Direction of Current in a Loop Near a Current-Carrying Wire?

[kimberlyann9]

Homework Statement

You are holding a conducting loop of copper and looking at its circle. Behind it is a long current-carrying wire carrying the current from left to right. As you pull the loop toward you, what is the direction of current flow if any?

A)No way to tell
B)Counter-clockwise
C)the applied field is tangent to the loop
D)Clockwise
E)None at all

Homework Equations

emf=-d(magentic flux)/dt

Not too sure what to do here...

Welcome to PF, kimberlyann9!

What can you say about the direction of the magnetic field?

And how would you normally calculate a magnetic flux?
