A rod of length $L$ is pivoted at one end and swings around at an angular frequency $\omega$ with its other end sliding along a circular conducting track. A magnetic field $B_{\rm in}$ is oriented perpendicular to the plane of rotation of the rod as shown. The pivot point and the outer ring are connected by (fixed) wires across a resistance $R$ with a voltmeter and ammeter inserted in the circuit as shown. What do the voltmeter and ammeter read?
