How to Measure a Magnetic Field Using a Generator
Kibble says, okay, that's great. Let's do another experiment with the same apparatus. Let's open up the leads on that coil. And the coil is going to be in the same magnetic field. Let's take the leads from that thing and connect it to a voltmeer. Now move the coil in the field of the magnet. This is what a generator does. The current will be generated by the generator moving in a magnetic field. It generates current. What we're going to do is measure the voltage that is generated. We're not going to let current flow. That's why we call this the velocity mode. But we don't worry about making all these other
