If one-inch and two-inch diameter bars were magnetized by passing the same current through them, the magnetic fields would be
-
The same for both.
-
Stronger in the two-inch diameter bar.
-
Weaker in the one-inch diameter bar
-
Stronger in the one-inch diameter bar.
That's Correct!
It's Wrong!
The magnetic field generated by a current-carrying wire is directly proportional to the current and inversely proportional to the distance from the wire. In this case, the current passing through both the one-inch and two-inch diameter bars is the same. Since the distance from the wire is also the same for both bars (assuming they are of the same length), the magnetic fields generated by them will be the same.
