- Can you enumerate how many different "right hand rules" (RHR) there are for electromagnetism? Specifically, there are two variants which I'm trying to figure when to use which. See attached figure for one variant. And the second variant describes the RHR as pointing your right index finger in the direction of the current, and then your fingers will curl in the direction of the magnetic field. See how the second variant only has two parts? Index finger, and rest of fingers curl in direction of B. So when to use the first variant, as it has 3 parts. And is the V (index finger) in the first variant the same as current (index finger) in the second variant? And now for a more practical application. Can you describe which RHR was used to answer the 3 questions below? #1. A current carrying loop of wire lies flat on a table top. When viewed from above, the current moves around the loop in a counterclockwise sense. For points OUTSIDE the loop, the magnetic field caused by this…This quiz is about reading off the information on the oscilloscope grid. Voltage is vertical, and the reading will always be in divisions and hash marks. Four hash marks divide each division into five smaller intervals, to make it easier to measure a fraction of a division. The voltage division number in the reading will be 0 through 8 -- the bottom line is zero, the top line is 8, and the hash mark will be 0 to 4. The horizontal axis is time, and the time scale is (hopefully) properly calibrated. There are ten divisions total. Each division is divided up by five hash-marks on the central horizontal line, to make measuring the time easier. If measured from the left side, the central line would be five divisions away, and would be div 5. One sets the voltage and time units per division on the oscilloscope. The time knob is visible in the introductory figures. The voltage isn't calibrated, though. It will always be referred to in div. Review the grid above. The time is 3 div,…At the points of the angles of an equilateral triangle with a side length of 30 cm, the electric charges are 2uC, 2 uC, and 3uC, respectively.
