Resistive Magnestism

  • The magnetic flux density \(B\) is changing in magnitude at a constant rate \(dB/dt\).A given mass \(m\) of copper,drawn into a wire of radius \(a\) and formed into a circular loop of radius \(r\) is placed perpendicular to the field \(B\).The induced current in the loop is \(i\).The resistivity of copper is \(p\) and the density is \(d\).The value of induced current \(i\) is ..
