For nearly all models of induction cooktops, a cooking vessel must be made of, or contain, a ferrous metal such as cast iron or some stainless steels. The iron in the pot concentrates the current to produce heat in the metal. If the metal is too thin, or does not provide enough resistance to current flow, heating will not be effective. Most induction tops will not heat copper or aluminum vessels because the magnetic field cannot produce a concentrated current; ''all metal'' induction tops use much higher frequencies to overcome that effect. Any vessel can be used if placed on a suitable metal disk which functions as a conventional hotplate.

To maintain lactation, a dairy cow must be bred and produce calves. Depending on market conditions, the cow may be bred with a ''dairy bull'' or a ''beef bull.'' Female calves (heifers) with dairy breeding may be kept as replacement cows for the dairy herd. If a replacement cow turns out to be a substandard producer of milk, she then goes to market and can be slaughtered for beef. Male calves can either be used later as a breeding bull or sold and used for veal or beef. Dairy farmers usually begin breeding or artificially inseminating heifers around 13 months of age. A cow's gestation period is approximately nine months. Newborn calves are removed from their mothers quickly, usually within three days, as the mother/calf bond intensifies over time and delayed separation can cause extreme stress on both cow and calf.

The ''will they or won't they'' tension between Jim and Pam is a strong storyline in the early episodes of The Office, encompassing much of Seasons 1 to 3. In the opener of Season 4, the two characters are revealed to be dating, and as such, other character romances, such as the romance between fellow co-workers Dwight Schrute and Angela Martin, begin to move more toward the forefront of episodes. In Season 6, Jim and Pam are married in the season's 4th and 5th episodes (hour long), a feat considered noteworthy by many television critics, as bringing together the two lead love interests in a television series is often thought to be a risky venture. Their child is born in the second half of the season, during another hour long, ''The Delivery''. Pam and Jim's second child is born during season 8. In season 9, their marriage becomes strained when Jim takes up a second job in Philadelphia. They ultimately decide to leave Dunder Mifflin together so Jim can pursue his dream job.
