Question concerning the mechanics of a magnet's attractive force

In summary, the question is whether the force exerted by a magnet changes if the distance between the magnet and the body remains the same but the direction of the magnet is changed (tilted). The answer may depend on the type of magnet and the material of the body. One way to determine if a bar is made of soft iron or is a bar magnet is by observing the behavior of the bars when rotated around their midpoints.

Does a force exerted by a magnet change if we do not change the distance between a magnet and the body, but change the direction of the magnet (tilt)?

:welcome:

You need to attempt this question yourself. What do you think?

By the way, why no equation?

What shape magnet? Horseshoe magnet, bar magnet, cylindrical magnet? Try using Google Images to find images of the lines of force coming out of the poles of the type of magnet you are asking about. See if that helps... :wink:

I think the answer depends on what the "body" is.

Consider an actual physical situation, then ask the question again. For example, you have a bar magnet and an iron rod at some distance apart with their axes along the same line. Rotate the magnet about its mid point by 180o. Does the force that the magnet exerts on the rod change? What if the iron rod is replaced with an identical magnet, initially oriented so that the north poles of the two face each other, and then one of the magnets is rotated?

Interesting question: You are given two identical-looking bars and you are told that one is a piece of soft iron and the other a bar magnet. How can you tell which is which?
 

1. What is the mechanism behind a magnet's attractive force?

The attractive force of a magnet is due to its magnetic field, which is created by the alignment of its electrons. When two magnets are brought close together, their magnetic fields interact and cause them to either attract or repel each other depending on their orientation.

2. How does the distance between two magnets affect their attractive force?

The strength of a magnet's attractive force decreases as the distance between two magnets increases. This is because the magnetic field weakens with distance, making the force of attraction between the two magnets weaker.

3. Can a magnet's attractive force be increased?

Yes, a magnet's attractive force can be increased by either increasing its size or by using a stronger magnetic material. Additionally, the magnetic field strength can be increased by aligning the magnet's electrons in the same direction.

4. Are there any materials that are not affected by a magnet's attractive force?

Yes, there are materials that are not affected by a magnet's attractive force, such as plastic, wood, and glass. These materials do not have magnetic properties and cannot be magnetized.

5. Can a magnet's attractive force be turned off or on?

No, a magnet's attractive force cannot be turned off or on. It is an inherent property of the magnet and is always present as long as the magnet exists. However, the strength of the attractive force can be changed by altering the magnet's properties.
