The direction of the magnetic force on the wire is west.
The magnetic force acting on the moving protons acts northward in the horizontal plane. If the thumb is up (current flows vertically up), the wrapped finger will be counterclockwise.
Therefore, the direction of the magnetic field is counterclockwise. Here, the magnetic field is pointing upwards (vertical magnetic field) and the electrons are moving east. Applying Fleming's left-hand rule here, we can see that the direction of force is along the south direction.
As the change in magnetic flux increases upwards, Lenz's law indicates that the induced magnetic field of the induced current must resist and the inside of the loop must be directed downwards. Using the right-hand rule, we can see that a clockwise current is induced.

Elements with the largest atomic radius are found in the lower left hand of the periodic table.
Answer:
Approximately
.
Explanation:
The average speed of a vehicle is calculated as:
.
In this question, the total distance is
.
The unit of the speeds in this question is meters per second, while the unit of distance is kilometers. Convert the unit of distance to meters:
.
