Changing Field

The animation shows the top view of a four wire conducing loop and a galvanometer.  Current flowing into the + terminal, i.e., counterclockwise in the loop, will deflect the meter to the right.   Plot the magnetic field passing through the loop during the time interval t=0 to t=10.  Assume the field is zero at t=0.    Start.

Script Example

<script language="JavaScript"> 
function boft(){
    document.Faraday.setDefault();
    document.Faraday.setFieldFunction("step(10-t)*min(0.2*t,2-0.2*t)");
    document.Faraday.setPosFunction("25");
    document.Faraday.setMaxTime(11);
    document.Faraday.setCycle(false);
    document.Faraday.start();
}
</script>
