[Physics] Does a change in electron’s direction affect direction of force

electromagnetism

A current carrying conducting wire is placed in a magnetic field, and hence, accelerates. Assuming the wire is moving in a constant magnetic field, will the electrons change direction due to the field?

If so, would that change the direction of the Lorentz force acting on the conductor?

Will the electrons ''bending'' in such a wire alter the direction of the force acting on the wire?

Best Answer

How are the two forces experienced in practical circumstances?

  • in a motor, the induced electric field is called back emf and it opposes the voltage applied at the terminals of the motor.
  • in a generator, the induced mechanical force is called amateur reaction or torque reaction and it tends to make the generator slow down or oppose whatever machine is been used to turn the generator.

In an ideal motor or generator (100% efficiency), the change in force would only be directional i.e.,

  • from electric (Iy) to mechanical (Fy) or
  • from mechanical (vx) to electric (Ey).
