To study Earth’s magnetic field using a compass, natal bar magnet wire plotting magnetic field lines and tangent galvanometer.pdf

Let me explain. To study Earth’s magnetic field, you can use a compass needle, a bar magnet, and a tangent galvanometer. Here are the steps: Bar Magnet Placement: Place the bar magnet in the middle of a large piece of paper. Mark the outline of the magnet and indicate its poles. Plotting Compass: Use a plotting compass (a small compass with a freely rotating needle). Position the compass near one pole of the bar magnet. Mark where the compass needle points. Moving the Compass: Move the compass so that the back of the compass aligns with the previous mark. Mark where the needle points again. Repeat this process until the compass reaches the magnet’s other pole or the edge of the paper. Drawing Field Lines: Connect the marked points with a smooth curve. Add an arrow to show the direction of the magnetic field. Repeat the process from different starting points around the magnet to draw more field lines. Tangent Galvanometer: A tangent galvanometer measures the strength of the magnetic field. It uses the tangent of the angle between the compass needle and the magnetic field direction. Remember, magnetic field lines never cross, go from north to south, are continuous, and are closer where the field is stronger. Have fun with your project THANK YOU..
