The ONLY reason for a coil arcing is a break down in the insulation. Look to see if the rubber sheath is intact and check that the coil itself for a hairline crack. I find it far better to check in a dark garage. One last thing, has the positive pole been bent?
I have a similar problem with a kawasaki mower. it was running fine, emptied the catcher and wouldn't restart. Found plug fouled, no start with a new plug. removed coil, and with an ohm meter tested continuity of poles to each other, inconclusive. found a good coil from a different B&S mower and compared readings. Kawasaki had continuity with plug lead and center pole on pick-up, B&S did not. I assume the center pole is grounding out the plug lead, so I will replace the coil and see.
it does not run smoothly and not all plugs fire when supposed to Addition to above: No spark or intermittent spark, a problem that was fairly common back when distributors had vacuum advances was that one of the wires going to the pickup coil (pole piece) would break from the back and forth movement of the pickup as the vacuum advance would move it to control the timing, symptoms would be no start or that it would start and when you put a load on the engine and the vacuum dropped the vacuum advance would start to move the pickup coil, the broken wire would open the circuit and the spark would die.To check this problem was fairly simple by removing the cap & rotor and tugging lightly on the wires where they go into the pickup coil/pole piece, if one of the wires was broken you could see it and knew you had to replace the pickup coil which GM called a pole piece (magnetic pickup coil and pole piece are the same thing).
That depends on the direction in which the coil of wire is wound.
Yes, and when you reverse the current flow, the north and south pole switch ends.
15 to 40 ohms.
The poles of the solenoid depend on the direction of the current through the coil. The current reverses if you just reverse the polarity of the voltage between the ends of the coil. Heck, if you energize the coil with AC, you can do that 120 times every second.
a speaker uses a voice coil a coil copper wire and a magnet and pole to vibrate a cone
It is a pole for fishing, a fishing pole. To be a fish pole, the pole would have to be made out of fish or it would have to be a pole that a fish uses.
The concave pole pieces focus the magnetic field onto the coil, enhancing sensitivity. The soft-iron cylinder helps to guide the magnetic field lines, allowing for efficient interaction with the coil. Both components work together to improve the performance and accuracy of the moving-coil galvanometer.
some horses will have to be tied to more than one pole, e.g. 6 to first pole, plus 1 tied to first and second, 6 tied to second pole, plus 1 tied to second and third, 6 tied to third pole, plus 1 tied to third and forth, 6 tied to forth pole, plus 1 tied to forth and fifth, 6 tied to fifth pole, plus 1 tied to fifth and sixth, 6 tied to sixth pole, plus 9 tied to the last pole =50.
Field pole winding is also called Field coil. Field coil is an electromagnet used to generate a magnetic field in an electromagnetic machine, typically a rotating electrical machine such as a motor or generator.
Suppose if u r using four pole stepper motor. keep the first coil on then energize second coil. and then again energise the first coil instead third coil. you will get reversed now.. all the best
