A diamagnetic substance when placed gently in a magnetic field moves

Options

A. From weaker to the stronger parts of the field
B. From stronger to the weaker parts of the field
C. Perpendicular to the field
D. Does not move

Answer

To solve the question regarding the behavior of a diamagnetic substance when placed in a magnetic field, we can follow these steps:

### Step 1: Understand the properties of diamagnetic substances
Diamagnetic substances are materials that are weakly repelled by a magnetic field. They do not retain any magnetization in the absence of an external magnetic field.

### Step 2: Analyze the magnetic field
In a magnetic field, there are regions of varying strength. The field is stronger near the poles of a magnet and weaker further away from them.

### Step 3: Consider the behavior of diamagnetic substances in a magnetic field
When a diamagnetic substance is placed in a magnetic field, it experiences a force that causes it to move. Since it is repelled by the magnetic field, it will tend to move from regions of stronger magnetic field strength to regions of weaker magnetic field strength.

### Step 4: Conclusion
Therefore, when a diamagnetic substance is placed gently in a magnetic field, it moves from the stronger part of the field to the weaker part of the field.

### Final Answer
A diamagnetic substance, when placed gently in a magnetic field, moves from the stronger part of the field to the weaker part of the field.
