A 50-turn circular loop has a radius 2.4 cm. It is oriented so that the magnetic field lines are normal to the area of the coil. Suppose that the magnetic field is varied so that B increases from 0.12 T to 0.32 T in 1.9 ms. Find the average induced emf in the coil.

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
