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 "
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
Direction of Current, according to Lenzs 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?
electromagnetism - Why does a magnetic field go anticlockwise of the . . . The magnetic field doesn't go anywhere We conventionally draw field lines going from North to South, but that's just a convention So the choice of clockwise vs anticlockwise is just a convention If we decided field lines went from South to North then the field lines would go anticlockwise not clockwise
Direction of magnetic field in a solenoid - Physics Stack Exchange The north and south pole of a solenoid depends on two factors One, the direction of the current flow and two, the direction of the winding (clockwise or counter-clockwise) Start by determine the positive pole of the power source (e g: battery), then the end of the solenoid that you are going to connect to it Now, looking down the solenoid tube determine what direction is the winding If
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
When are torques positive or negative? - Physics Stack Exchange hi, i'm having a little trouble with this problem the correct answer is D, but i got B because i'm confused about the signs of T2 and T1 it makes sense to me that T2 is positive in the equation, because it's a negative quantity, and the pulley will rotate clockwise, and it avoids a double negative but why is T1 being subtracted? it's a
What does it mean for a galaxy to rotate clockwise? 6 There was a recent news article that said nearly one-third of the galaxies in a survey rotated anticlockwise, and over two-thirds showed clockwise movement What does that mean exactly? Surely clockwise vs anticlockwise is dependent on the angle you make the observation? What if the galaxy is viewed perpendicular to the axis of rotation for
