The figure shows the motion of electrons in a wire that is near the N pole of a magnet. The wire will be pushed
Correct answer: D. Upward
- A. Toward the megnet
- B. Downward
- C. Away from the megnet
- D. Upward
Explanation
Option D is correct. If the motion of the current is near the north pole, the wire will be pushed upwards. Current is the rate of change of charges with respect to time. First, we must know that the flow of current is opposite that of the electron. If there is no flow of electrons, there won't be a flow of current and since the electrons are moving downwards, the current is expected to flow in the upward direction which determines the direction of motion of the wire. or F=I(LxB)Right hand rule is applied only on the direction of conventional current. In the given case the direction of current is due to electron and it is opposite to conventional current. So, By right hand rule the direction of fore will be upward.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
