question:
Question: On a Physics specification, it says: 6.7 Know how to use two permanent magnets to produce a uniform magnetic field pattern. Isn't it "produce an uniform magnetic field", or is the existing "produce a uniform magnetic field pattern" correct?
Answer: The word uniform begins with a palatal approximant /j/. The palatal approximant is a consonantal sound, even though the letter itself is a vowel. Since we use the pronunciation of the word following the article to determine whether we use "a" or "an", and because it is pronounced starting with a consonant, we use "a". Thus, the original sentence is correct. Just for the sake of completeness, the letter "u" can also have a vowel sound, such as in the word "umbrella", which begins with an open-mid back unrounded vowel //.
answer:
yes

Question: Is there a word for reverse homesickness? Let's say, if you visit a place, and you like it so much, you don't want to leave.
Answer: The opposite of homesick is "Wanderlust" when you have a big desire for traveling or going to a journey and exploring the world. However there was an interesting comment in a forum about the opposite of homesickness: It's still homesick. "Boy, I am homesick!" "But you live at home." "Yeah, and I'm sick of it!" hope it helps.

yes
