In summary, the conversation discussed the concept of current, which refers to the opposite direction of motion of electrons in a wire. It was also mentioned that this can be treated similarly to two parallel wires with current in them. The conversation also touched upon using the equation Fm = qvbsin theta to calculate the force on electrons in a wire. It was confirmed that this is possible by substituting the appropriate values. The conversation ended with a light-hearted comment of appreciation.

The current refers to the conventional current, opposite to the direction of motion of electrons in the wire, i.e., all electrons in the description moves in the same direction. Treat this as you do two parallel wires with current in them, then.

If I find out B of the wire, can I sub the q/v/sin theta of the electron into Fm = qvbsin theta to get the Fm then?

Beautiful. Thanks guys!
Related to Can Electron Movement Be Controlled by Magnetic Fields?
1. What is an electron?
An electron is a subatomic particle with a negative charge that orbits the nucleus of an atom. It is one of the fundamental particles that make up matter.
2. How are electrons affected by magnetic fields?
Electrons are affected by magnetic fields because they have a property called spin, which can be thought of as a tiny magnetic dipole. When an external magnetic field is applied, the spin of the electron aligns with the field, causing the electron to experience a force and move in a curved path.
3. What is the relationship between electrons and electricity?
Electrons are the carriers of electricity. When electrons move through a conductive material, such as a wire, they create an electric current. This flow of electrons is what powers electrical devices.
4. How do magnetic fields affect electric currents?
Magnetic fields can induce electric currents in conductive materials. This is known as electromagnetic induction. When a conductive material moves through a magnetic field, the changing flux of the field causes electrons to move and create an electric current.
5. How are electrons used in technology?
Electrons are used in a wide range of technologies, such as electronics, telecommunications, and medical imaging. In electronics, they are used to carry and control electric currents. In telecommunications, electrons are used in devices like transistors and diodes to amplify and switch electronic signals. In medical imaging, electrons are used in devices such as X-ray machines and MRI scanners to create images of the human body.
