1)If the magnet moves as shown in the diagram, the primary flux through the coil

  A. increases and points to the right.  
  B. increases and points to the left.  
  C. decreases and points to the right.  
  D. decreases and points to the left.



2) The magnetic flux is changing as it passes through two coils that are exactly the same. The induced voltage is greatest in the coil whose flux is changing fastest.
True
False

3) The primary magnetic flux through a coil is increasing. The induced magnetic flux is in the opposite direction as the primary flux.
True
False

The magnet moves as shown. The field of the magnet through the coil is:

fig

(a) to the left and the primary flux through the coil is decreasing.
(b) to the right and the primary flux through the coil is decreasing.
(c) to the right and the primary flux through the coil is increasing.
(b) to the left and the primary flux through the coil is increasing.

An N-turn square coil with side and resistance is pulled to the right at a constant speed in the presence of a uniform magnetic field acting per pendicular to the coil as shown in Figure P30.43. At , the right side of the coil has just departed the right edge of the field. At time , the left side of the coil enters the region where . In terms of the quantities , , , and , find the symbolic expression for

(a) the magnitude of the induced emf in the loop during the time interval from to ,

(b) the magnitude of the induced current in the coil,

(c) the power delivered to the coil, and 

(d) the force required to remove the coil from the field.

(e) What is the direction of the induced current in the loop? 

(f) What is the direction of the magnetic force on the loop while it is being pulled out of the field?
