1. The problem statement, all variables and given/known data James Clerk Maxwell used an equipment to confirm the nature of the magnetic field around a long, straight conductor. he found that no matter how large the current through the wire, the disk did not rotate at all. a. explain how this device can be used to determine the nature of the magnetic field around a conductor with a steady current. 2. Relevant equations none 3. The attempt at a solution By using the right hand rule.. the magnetic field is going to be horizontal and going in a counterclockwise direction... so why wouldn't the disk spin?
