Electromagnets work by aligning little regions of magnetic field in iron so they mostly point in the same direction. This produces a greatly strengthened magnetic field. This is correct.
 
  Electromagnets' domains are aligned by the current in the coil. 17 . If a normal D-cell battery is used in a device, for every 1.0 C of charge that moves through the battery, 1.5 J of work is done on the charge.

Question 2

Tectonic plates on Earth are moving rapidly geologically at some number of meters per year.
 
  What will be an ideal response?

Answer to Question 1

The potential difference supplied by the battery is the work done per unit charge:
1.5 J/C. Thus, the battery does 1.5 J of work on every coulomb of charge that passes
through the battery.

Answer to Question 2

Actually, the plates move centimeters per year.
