A long, straight wire extends into and out of the screen. The current in the wire is
| Out of the screen. | |
| There is no current in the wire. | |
| Into the screen. | |
| There is not enough information to tell the direction. |
Homework Answers
From the figure given in the question, compass needle is rotating in counter-clockwise direction.
Now, use the right-hand rule to identify the direction of magnetic field at the desired location. From right hand rule, point the thumb in the direction of current and curl the fingers around the line passing through the thumb. The curling direction of the fingers will give the direction of magnetic field.
Since the direction of rotation of the compass needle is counter-clockwise, the direction of magnetic field would also be in counter-clockwise direction.
So, the possible direction of current from right-hand rule must be out of the screen.

An infinitely long, straight, cylindrical wire of radius R carries a uniform current density J. Using symmetry and Ampere's law, find the magnitude and direction of the magnetic field at a point inside the wire. For the purposes of this problem, use a cylindrical coordinate system with the current in the +z-direction, as shown coming out of the screen in the top illustration. The radial r-coordinate of each point is the distance to the central axis of the wire, and...
