In the PHY104 lab, you are looking at a coil made from copper which lies flat on a table. A magnetic field of 0.01 T created by a permanent magnet points straight up and is passing through the copper coil.  Suddenly you notice that the magnetic field vanishes. According to the Lenz’s law what is the direction of the induced current in the coil while the magnetic field vanishes, when you look at it from above?

In the following circuit, which of the following is a valid expression derived either from the loop rule or junction rule for this circuit?  

A silver loop with the diameter of 12.0 cm and resistance of 0.60 Ω is located perpendicularly to the uniform magnetic field directed from the left to the right. If the magnetic field increases uniformly from 0.4 T to 2.0 T in 0.20 s, determine the magnitude of the emf induced in the loop?

Total revenues minus total costs equals _____.

Which of the following current carrying loops in an external B-field rotates clockwise? (The B-field lines are the gray lines.)

In an advanced Laboratory of EM wave in Madison, Mathew is studying the impact of the radiation  of an EM beam with an intensity of 120 W/m2. Determine the maximum value of the electric field? (c = 3.0 × 108 m/s,
