A straight line wire moving down through a magnetic field, will the induced current flows from which direction?

Answer 1

When a straight line wire moves down through a magnetic field, an induced current will flow in a direction that creates a magnetic field that opposes the change in magnetic flux. This is described by Lenz's law, which states that the direction of the induced current is such that it opposes the change in the magnetic field that is inducing it.

In this case, as the wire moves down through the magnetic field, the magnetic flux through the wire will increase. To counteract this increase in magnetic flux, the induced current will flow in a direction that creates a magnetic field that opposes the external magnetic field. This means that the induced current will flow in a direction opposite to the direction of the external magnetic field.

In conclusion, the induced current will flow in a direction opposite to the direction of the external magnetic field when a straight line wire moves down through a magnetic field.
