The facts on the card
The card carries these facts from its Wikipedia article.
- If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber, that coil has a self-inductance of 1 henry. The unit is named after Joseph Henry, the American scientist who discovered electromagnetic induction independently of and at about the same time as Michael Faraday in England.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Henry article was read about 52,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 47 and blocks with 21: each hit it takes is cut by 8 %.
How to get Henry
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
