When inserting a 2-layer lap winding, always lift the span. That is, install the coils such that each coil has one side in the bottom of a slot and one side in the top of a slot.

Winding over the span, or lazy-lapping, can prevent proper cooling in the buried coils and cause circulating currents if there are parallel circuits.

It is possible to pay a search engine for a placement in certain search results.

According to searchmetrics.com, these advertisements do not appear in natural search results. Instead, they appear in the sponsored results (usually on the right-hand side of the search engine’s results page) in response to a corresponding search term. The amount spent on advertising can be adjusted for a variety of factors. In addition, you can determine whether the advertisement appears regionally or nationwide. The fee for these ads is calculated using the number of clicks the advertisement attracts. The higher the advertising budget the better the position the website will get in a given search result. Search engine advertising can be particularly useful if a website is not appearing at the top of the search results because it is not yet well known or if there is a lot of competition for the search term being used.
