That video you posted explains pretty well, so please be more specific with your question.ENE said:ok, thanks.
How to do experiment Stewarttangent galvanometer?
ENE said:I mean what is the application of this experiment ?
is to find magnetic field by coil it self??
A magnetic needle compass is a navigational instrument that uses the Earth's magnetic field to determine direction. It consists of a magnetized needle that aligns with the Earth's magnetic field, allowing it to point towards the Earth's magnetic North pole.
A magnetic needle compass works by utilizing the Earth's magnetic field. The needle is suspended on a pivot point and is able to rotate freely. The Earth's magnetic field causes the needle to align with it, allowing it to point towards the Earth's magnetic North pole and thus indicate direction.
A magnetic needle compass is a reliable and easy-to-use tool for determining direction. It does not rely on any external power source and can be used in all weather conditions, making it a valuable tool for outdoor activities or navigation.
A magnetic needle compass is generally accurate within a few degrees, but its accuracy can be affected by external factors such as nearby metallic objects, strong magnetic fields, or incorrect handling. It is important to regularly calibrate the compass to ensure accuracy.
Yes, a magnetic needle compass can be used anywhere on Earth, as long as it is properly calibrated. However, the closer you are to the Earth's poles, the less reliable the compass may be due to the convergence of the Earth's magnetic field lines.
