A sensitive ammeter is connected to a wire loop and placed within the magnetic field of a strong horseshoe magnet. The ammeter shows a deflection when:
 a. the wire is moved parallel to the field. b. neither wire nor magnet is moving.
  c. the wire's axis is parallel to the field. d. the wire is moved perpendicularly to the field.

Question 2

A 0.20-kg block rests on a frictionless, level surface and is attached to a horizontally aligned spring with a spring constant of 80 N/m. The block is initially displaced 4.0 cm from the equilibrium point and then released to set up a simple harmonic motion. A frictional force of 0.3 N exists between the block and surface. What is the speed of the block when it passes through the equilibrium point after being released from the 4.0-cm displacement point?
 a. 0.45 m/s
  c. 0.72 m/s
  b. 0.63 m/s
  d. 1.2 m/s
