The magnetic force between a magnet and a magnetic substance can cause various effects. Let's analyze each option to determine which effect is NOT caused by this force:
a) Change of state: This refers to a change in the physical state of matter, such as solid to liquid or liquid to gas. The magnetic force between a magnet and a magnetic substance does not cause a change of state. State changes are typically caused by changes in temperature or pressure.
b) Change of shape: The magnetic force can indeed cause a change in the shape of a magnetic substance. When a magnet attracts a magnetic material, it can cause it to deform or take a different shape. This effect is commonly observed with iron filings aligning along the magnetic field lines of a magnet.
c) Change of size: The magnetic force can also cause a change in the size of a magnetic substance. For example, when a magnet attracts a magnetic material, it can cause it to shrink or expand, depending on the direction of the force. This effect is utilized in devices such as electromagnets and speakers.
d) Change of chemical composition: This is the correct answer. The magnetic force between a magnet and a magnetic substance does not cause a change in the chemical composition of the substance. Chemical composition changes involve the rearrangement of atoms and the formation or breaking of chemical bonds, which are not influenced by magnetic forces.
In summary, the magnetic force between a magnet and a magnetic substance can cause changes in shape and size but does not cause changes in state or chemical composition.
