Clockwise

Understanding clockwise requires examining multiple perspectives and considerations. What does "clockwise" mean, exactly? - Physics Stack Exchange. The answer too makes explicit reference to the right hand rule to define clockwise. One answer to Applying the right-hand rule for magnetic forces explicitly uses the right hand rule, and explains that it is useful because the direction is " counter-clockwise or clockwise depending on what side of the plane you are looking at ".

How does Earth rotate on its axis, clockwise or anti-clockwise?. This is essentially a meaningless question unless you specify a system with respect to which you define both clockwise and anti-clockwise. If you don't do this, then there really is no way to answer: when seen from above the North pole, the Earth rotates in a counter-clockwise direction, whereas when seen from above the South pole, it rotates ... Why is Coriolis effect responsible for COUNTER-clockwise rotation in ....

This perspective suggests that, so why does a projectile rotate clockwise, but air moves counterclockwise? The cases of ballistic motion and motion of air mass are intrinsically different, for several different reasons. The motion of a projectile is in first approximation a case of orbital motion (it's just that it's along an orbit that intersects the Earth surface.) Why does earth spin counter-clockwise?

This perspective suggests that, but there is a clear reason why it is clockwise: Earth's spin cuases an apparent motion of the sun during the day, which causes shadows to turn around objects. This was used to construct sundials to measure the time, and so the shadow's motion defined what we call clockwise, as the direction was transferred to later mechanical clocks. Why is a clockwise moment negative by convention?. My physics book states that by convention a clockwise moment is said to be negative and an anti-clockwise moment is said to be positive.

I'm curious about the origin of this convention. Do electrons in an atom always have the same 'direction'?. Calling one clockwise and the other anticlockwise doesn't quite get the difference across.

But the angular momentum is genuine. Check out the Einstein-de Haas effect, which demonstrates that spin angular momentum is indeed of the same nature as the angular momentum of rotating bodies as conceived in classical mechanics. Direction of Current, according to Lenz's law, from induced EMF.

The Arm PQ is moved to the left side thus decreasing the area of the rectangular loop. This results in a decrease in magnetic flux in the Downward (inside the page) direction. Hence, according to lenz's law, the induced current should be in Clockwise direction but the book says the opposite. Am I missing something? or is the book wrong?

Why is induced electric current moving clockwise/counterclockwise?. Hence for north pole approaching or a south pole moving away, the current runs counter-clockwise. When the north pole is moving further away or the south pole is moving closer, the opposite is true: the change in flux is negative, thus the line integral of the electric field is positive.
