Question

A large copper hoop with radius of 1 m is located near the Earth's surface in a region where the Earth's magnetic field dips to the right at a 60degree angle. Assume the magnetic strength is about 10-4 T in this region. The hoop is open to the right, with the plane of the hoop perpendicular to the ground. It is held in that position as it is moved to the right at 2 m/s. Estimate the magnetic flux through the hoop. 0 0.5n times 10-4 Wb pi times 10-4 Wb 2pi times 10-3 Wb 3pi times 10-3 Wb The hoop is again open to the right, with the plane of the hoop perpendicular to the ground. It is held in that position as it is moved to the right at 2 m/s. Estimate the EMF induced through the hoop. 0 1 times 10-4 V 3 times 10-4 V 5 times 10-4 V 9 times 10-4 Which action with the hoop will induce the largest current in the hoop while it is in the field? Moving the vertical hoop to the right at a constant velocity. Rotating the vertical hoop around a horizontal axis that is perpendicular to the plane of the hoop. Rotating the vertical hoop around a horizontal axis across the hoop, in the plane of the hoop. Dropping the hoop in such a way that it fall straight to the ground without rotating. Holding the hoop stationary in the position described above.
