Don't worry about the forces the wires exert on each other. You are asked to find the field at point P. What's the field from a current-carrying wire?Cici2017 said:
Magnetic field?Doc Al said:
Yes. So how do you find the magnetic field surrounding a current-carrying wire?Cici2017 said:
Wrong formula. Again, you are not finding the force on a current-carrying wire, but the field surrounding it.Cici2017 said:
Yes! Read the above link.Cici2017 said:
The direction of the magnetic field is defined as the direction in which a north magnetic pole would be pushed by the field. This is typically represented by lines of flux that extend from the north pole to the south pole of a magnet.
The direction of the magnetic field is determined by the orientation of the magnetic field lines, which are based on the direction of the current flow. The right hand rule is often used to determine the direction of the magnetic field, with the thumb pointing in the direction of the current and the fingers curling in the direction of the magnetic field lines.
Yes, the direction of the magnetic field can be reversed by changing the direction of the current flow. This can be achieved by reversing the polarity of a magnet or by changing the direction of the electric current in a wire or coil.
The direction of the magnetic field determines the north and south poles of a magnet, which in turn affects the behavior of the magnet. Like poles repel each other, while opposite poles attract. The direction of the field also determines the strength and shape of the magnetic field around the magnet.
No, the direction of the magnetic field can vary depending on the location and orientation of the magnet or current. In some cases, the direction of the magnetic field may also change over time due to external factors such as the Earth's magnetic field or electromagnetic interference.
