  • 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 and how does the clock rule of electromagnetism (i. e. current . . .
    Why and how does the 'clock rule' of electromagnetism (i e current flows clockwise as seen from the south pole of an electromagnet) work? [duplicate] Ask Question Asked 10 years, 1 month ago Modified 9 years, 7 months ago
  • 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 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
  • Difference in winding a coil clockwise vs counter clockwise
    1 I was watching a YouTube video on the difference of winding a coil clockwise vs winding a coil counter clockwise It said the poles would be opposite using the same battery configuration I've been thinking about this and it seems to me the poles would be the same regardless of the direction of the wind
  • 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
  • Why does earth spin counter-clockwise? - Physics Stack Exchange
    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
  • 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
  • How to determine the direction of induced current flow?
    It is "clockwise" when you look at your hand thumb-on, or when you look at the change pointing towards you This means that if a current follows that curling, it goes to a higher voltage; or if it opposes that curling, it goes to a lower voltage
  • Is it true that water go down the drain counterclockwise in the . . .
    Many websites say that water drain in different directions in Northern, Southern hemispheres Some people say that Coriolis effect causes it Some people say that it's not true
