The magnetic flux through each of five faces of a die (singular of dice) is given by ΦB=±2N Wb, where N(=1 to 5) is the number of spots on the face. The flux is positive (outwards) for N even and negative (inward) for N odd. What is the flux through the sixth face of the die?

A Gaussian surface in the shape of a right circular cylinder with end caps has a radius of 5.60 cm  and a length of 80.0 cm . Through one end there is an inward magnetic flux of 25.0 μWb. At the other end there is a uniform magnetic field of1.60 mT , normal to the surface and directed outward. What are the (a) magnitude and (b) direction (inward or outward) of the net magnetic flux through the curved surface?
