cylindrical volume of radius R has a uniform axial magnetic field B, which is increasing at a rate of (dB)/(Dt) = alpha Ts^(-1). A chord (AB) of the circular cross section of the cylindrical region has length L.Calculate the line integral of induced electric field (int_(A)^(B) vec(E) vec(dl)) as one moves along the chord from A to B. Try to find the answer without actually performing the integration. Is the value of integral same if one moves along the arc from A to B ?
