In theory, a current carrying wire will have a magnetic field. What are various ways to run a current through wire? How can you tell you have a magnetic field? What tests could you do?
The charges moving inside a conductor experience a magnetic force if the conductor is placed in a magnetic field, resulting in a potential deference called Hall Voltage. If the direction of B (into the plane of the paper) and / (towards up) are as shown in the figure, In which face of the conductor does the electron tend to accumulate due to this effect. a) Face 1 b) Face 2 c) Face 3 d) Face 4
