A Hollow Cylindrical (Inner Radius = 2

question 72

Multiple Choice

A hollow cylindrical (inner radius = 2.0 mm, outer radius = 4.0 mm) conductor carries a current of 24 A parallel to its axis. This current is uniformly distributed over a cross section of the conductor. Determine the magnitude of the magnetic field at a point that is 5.0 mm from the axis of the conductor.

• A) 0.96 mT
• B) 1.7 mT
• C) 0.55 mT
• D) 1.2 mT
• E) 0.40 mT

Definitions:

Temporary Dipole

A temporary dipole occurs when there is a short-lived imbalance of electron density within a molecule, causing a temporary separation of charges.

Intermolecular Force

The forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions).

Dispersion Forces

Weak forces resulting from temporary polarization of molecules due to the movement of electrons, also known as London dispersion forces.

Van Der Waals

Weak forces of attraction between molecules, named after Dutch physicist Johannes Diderik van der Waals, significant in the properties of gases and liquids.
