Faraday's Law

In our project, we will explain the mechanism behind magstripes, or magnetic card stripes. We will explain the process of swiping a card, thereby storing and receiving data, with the principles of Faraday’s Law (which explains how induced EMF’s [aka voltage] result from varying magnetic fields, magnetic flux, and induced currents). Our project will primarily be theoretical, but we will also delve into the experimental by measuring the maximum and minimum velocities accepted by card readers around Vassar’s campus.
