Web1. The direction of the magnetic field is tangent to the field line at any point in space. 2. The strength of the field is proportional to the closeness of the lines. 3. Magnetic field lines can never cross. 4. Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole. Web22. In the textbook, it said a wave in the form y ( x, t) = A cos ( ω t + β x + φ) propagates along negative x direction and y ( x, t) = A cos ( ω t − β x + φ) propagates along positive x direction. This statement looks really confusing because when it says the wave is propagating along ± x direction, to my understanding, we can drop ...

Web21 aug. 2014 · Assuming you define current as the direction which positive charge moves, there is no assymetry. If your charge carriers are negatively charged, then you must use I → − I. The magnetic field generated by this current still obeys the right hand rule, so there is no asymmetry. Aug 21, 2014 at 6:46. A hand rule is always a asymmetry. Web22 feb. 2024 · 4 Answers. 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. bonbonne gaz decathlon
