Worked Solution & Example Answer:The diagram shows a bar magnet - Leaving Cert Physics - Question b - 2016
Step 1
Copy the diagram and show on it the magnetic field lines around the magnet.
Answer
To complete this part, draw the bar magnet, labeling the North (N) and South (S) poles. Then, illustrate the magnetic field lines emerging from the North pole and curving around to enter the South pole. Ensure that the lines are evenly spaced and show the correct direction of the magnetic field, which flows from North to South.
Step 2
Describe an experiment to plot the magnetic field lines around the magnet.
Answer
Apparatus: Compass or iron filings.
Procedure: Use a compass or iron filings to locate the magnetic field lines. If using a compass, place it on a sheet of paper over the magnet and mark the direction of the needle; move the compass to different locations around the magnet to draw a complete set of lines. If using iron filings, gently sprinkle them on a piece of paper placed over the magnet and tap the paper lightly, which will cause the filings to align along the magnetic field lines.
Detail: In both setups, you can draw the dots or lines of the magnetic field from North to South and identify the orientation of the field.
Naming: Mark the poles of the magnet (N and S) and ensure lines are curved as they exit the magnet.
