22M.1.HL.TZ1.22

A conductor is placed in a uniform magnetic field perpendicular to the plane of the paper. A force F acts on the conductor when there is a current in the conductor as shown.

The conductor is rotated 30° about the axis of the magnetic field.

What is the direction of the magnetic field and what is the magnitude of the force on the conductor after the rotation?

Examiners report

This question requires careful reading by the candidate. Candidates needed to appreciate that the rotation relative to the magnetic field axis still produces a 90 degree angle between the conductor and the field. Option D was a very effective distractor for students.
