The diagram shows a clockwise current I in a circular coil placed in a uniform magnetic field B with the plane of the coil perpendicular to the magnetic field - AQA - A-Level Physics - Question 27 - 2018 - Paper 2

When a current-carrying conductor is placed within a magnetic field, it experiences a force due to the Lorentz force, given by the equation:

$extbf{F} = q( extbf{v} imes extbf{B})$

For a circular coil with clockwise current in a perpendicular magnetic field, the right-hand rule shows that the force causes the coil to rotate. Specifically, the top of the coil will move out of the page while the bottom moves into the page. Thus, the correct answer is:

A: It rotates about the axis with the top moving out of the page.
