1. The problem statement, all variables and given/known data A current is induced in a loop by something happening with current in a long straight wire near the loop. What could be happening? (There are two possibilities. Neither the wire nor the loop is moving.) 2. Relevant equations Ampere's Law Faraday's Law 3. The attempt at a solution I'm pretty sure I know one of the possibilities. I said that one possibility is that the current in the straight wire is changing. This changing current will create a magnetic field. This created magnetic field will then induce a current in the loop. I cannot think of the other possibility if the wire and loop are not moving. Any help would be appreciated.
