MCAT Question of the Day

    Q:

    		 Metallic hydrogen is a theoretical phase of hydrogen that is predicted to form at ultra-high pressures. In this state of matter, electrons are delocalized. For gas giants like Jupiter, composed primarily of hydrogen, is known to have a spinning core. One key observation is that Jupiter also has a very strong magnetic field. This magnetic field is most likely caused by:
    		 

    A

    		 Hydrogen, which has nonzero magnetic momentum of its sole electron, is inherently magnetic.

    B

    		 The spinning of the metallic core creates a current, which in turn generates a magnetic field.

    C

    		 The magnetic field is caused by spinning of the hydrogen nucleus.

    D

    		 Delocalized electrons always produce a magnetic field.
