rectangle loop pass through magnetic field
Top Image
The gray rectangle in the figure above represents a region of uniform magnetic field directed out of the page. A square loop of wire of side `s` is in the plane of the page and is pulled at constant speed `v` through the field. Which of the following could show the current in the loop as a function of the positions of the right edge fo the loop? Rectangle loop moves into the magnetic field: magnetic flux inside the loop is increasing. clockwise current in the loop. Rectangle loop moves inside the magnetic field: magnetic flux inside the loop keep same . No current in the loop. Rectangle loop moves out of the magnetic field: magnetic flux inside the loop is decreasing. counterclockwise current in the loop ( negative `I`).
