In summary, the conversation discusses the property of total angular momentum and how it relates to spinning tops and magnets. The spinning top's ability to twist when turned reveals the existence of angular momentum inside, which cannot be seen by examining the non-rotating outer shell. Permanent magnets contain large numbers of electrons and nuclei, and their alignment of spin or orbital angular momentum makes them magnetic. However, despite containing internal angular momentum, a magnet will not twist when a force is applied to its outer shell.

A spinning top has the property to twist when turned. If it is placed in a tilted position, it will not fall over downwards. Instead it will precess around the vertical position and remain at a constant tilt.

This is the property of total angular momentum. Suppose that a spinning top were placed inside an outer shell, which is not spinning but which is affixed to the ends of the axis.

Such outer shell would then also resist turning and twist sidewards instead. Even though the outer shell is not rotating at all. The property to twist when turned reveals the existence of angular momentum inside, which cannot be verified by examination of the nonrotating outer shell.

Now, permanent magnets contain large numbers of electrons and nuclei inside, and are magnets because the spin or orbital angular momenta are aligned, not paired (as in diamagnetic and antiferromagnetic objects) nor randomly distributed (as in paramagnets).

Does this mean that on an attempt to turn a magnet by applying a force in its outer shell, it would twist because its internal angular momentum, rather than yield to torque?

No, a magnet acts like a non-spinning object.
 

Related to Do Magnets Exhibit Twisting Due to Internal Angular Momentum?

1. Do magnets always twist when turned?

No, magnets do not always twist when turned. The direction of the twist depends on the orientation of the magnet's north and south poles.

2. What causes a magnet to twist when turned?

A magnet twists when turned due to the interaction between its north and south poles. This is known as the magnetic torque force.

3. Can a magnet twist in both directions when turned?

Yes, a magnet can twist in both clockwise and counterclockwise directions when turned, depending on the orientation of its poles.

4. How does the shape of a magnet affect its twisting when turned?

The shape of a magnet can affect its twisting when turned. Magnets with a longer and thinner shape are more likely to twist when turned compared to shorter and wider magnets.

5. Is there a limit to how much a magnet can twist when turned?

Yes, there is a limit to how much a magnet can twist when turned. This is known as the magnetic hysteresis limit. When this limit is reached, the magnet will no longer twist and will remain in its new orientation.
