What if anything is wrong task on the magnetic field of a long straight wire

Task – A long straight wire carrying a current is oriented perpendicular to the page. A compass can be moved around to show the orientation of the magnetic field.

A student experiments thoroughly with the arrangement and draws the following picture of the orientation of the magnetic field lines.

What if anything is wrong with the students diagram? Nothing, the diagram is fine The field lines point the wrong way The field should look like a bar magnet Some other answer 1 2 3 4 5

What is the reason for your answer? The compass needle points in the direction of the magnetic field The north pole of the compass is attracted to the south Magnetic fields always look like bar magnets Some other reason 1 2 3 4 5

How confident are you about your answer? Very Confident Somewhat confident Neutral Mostly guessing completely guessing 1 2 3 4 5
