Tilt the Loop, Lose the Flux

You'll learnwhat magnetic flux is: how much of a field actually passes through a loop, and which angle to measure.

A loop of wire sits in a magnetic field, facing it head on. Tilt the loop, and something falls all the way to zero while the field never changes at all. Twelve short steps; press Next for each one.

Before you start

What you're looking at

A magnetic field drawn as blue arrows, and a loop of wire sitting in it. The loop can tilt.

The question
