Uses
- Studying Earth’s Magnetic Field: It is used to detect the direction of the Earth’s magnetic field by aligning itself with the magnetic north-south direction.
- Calibrating Magnetic Instruments: The needle helps in calibrating magnetic instruments by providing a reference for direction.
- Detecting Magnetic Materials: It can be used to detect the presence of magnetic fields or magnetic materials in close proximity.
- Electromagnetic Experiments: It is used in experiments involving electromagnetism to demonstrate the effect of electric currents on magnetic fields, such as in Oersted’s experiment.
- Compass Demonstration: It can serve as a basic demonstration of how a compass works, showing the principle of magnetism.
- Measuring Deflection: In combination with electrical circuits, the magnetic needle can be used to measure deflections caused by magnetic fields, aiding in the study of electromagnetic principles.
