Magnetic substances are substances containing aligned dipoles. Dipoles are spinning electrons. In order for something to be magnetic, its dipoles must be aligned with each other, so that they face the same direction. The direction they face create a North end, while the opposite end creates a South end.
Some substances, known as ferromagnetic substances, have permanently aligned dipoles. Other substances, such as paramagnetic and dimagnetic substances, require an external magnetic field to align, or 'induce' the dipoles of the substance.
To conclude, magnetic substances contain dipoles which are permanently aligned, or can be aligned through the force of external magnetic fields.
Diamagnetic Substances are those Substances there is no resultant field as the magnetic field produce by both the spin and orbital motions of the electrons might add up to zero.
What else can I help you with?
Are most substances magnetic?
Technically all substances are magnetic in some way: it's either ferromagnetic (what most people would consider "magnetic"), paramagnetic (weakly attracted to a magnetic field), or diamagnetic (weakly repelled by a magnetic field). Not many substances are "magnetic" in the usual lay meaning of the word, though.
When the two substances are put in the same container they do not attract each other. Why does this happen?
Either one or both of the substances are not magnetic.
Is used to separate magnetic material other substances?
A magnet can be used to separate magnetic materials from other substances by attracting the magnetic material while leaving non-magnetic materials behind. This process is known as magnetic separation and is commonly used in recycling and mining industries.
What do magnetically soft substances do?
Magnetically soft substances are easily magnetized and demagnetized. They have low coercivity, meaning they can quickly change their magnetic orientation when exposed to a magnetic field. These materials are often used in applications where the magnetic state needs to be easily manipulated, such as in transformers or magnetic shielding.
The 4 magnetic materials?
The four main magnetic materials are iron, cobalt, nickel, and some alloys of rare earth metals. These materials exhibit strong magnetic properties and are commonly used in various applications such as electric motors, transformers, and magnetic storage devices.
What are magnetic and non magnetic substance?
Magnetic substances are those that are attracted to a magnet while non-magnetic substances are not attracted to a magnet.
Is oil a magnetic substance?
Oil is not magnetic, but magnetic substances can be made from it.
Are most substances magnetic?
Technically all substances are magnetic in some way: it's either ferromagnetic (what most people would consider "magnetic"), paramagnetic (weakly attracted to a magnetic field), or diamagnetic (weakly repelled by a magnetic field). Not many substances are "magnetic" in the usual lay meaning of the word, though.
How can one differentiate between paramagnetic and diamagnetic substances?
Paramagnetic substances are attracted to a magnetic field, while diamagnetic substances are repelled by a magnetic field. This difference is due to the presence of unpaired electrons in paramagnetic substances, which align with the magnetic field, whereas diamagnetic substances have all paired electrons that create a weak opposing magnetic field.
Are all metallic substances magnetic?
No

Is used to separate magnetic material other substances?

What are non magnetic substances?
In non-magnetic materials,the magnetic moments of individual atoms are randomly arranged giving net zero magnetic moment such that these materials are not affected when an external magnetiv field is applied
Can you provide examples of paramagnetic and diamagnetic substances and explain the differences between them?
Paramagnetic substances are those that are weakly attracted to a magnetic field, such as oxygen and aluminum. Diamagnetic substances, on the other hand, are weakly repelled by a magnetic field, like copper and bismuth. The key difference between them lies in their response to magnetic fields: paramagnetic substances are attracted, while diamagnetic substances are repelled.
How does a magnetic stirrer work to mix substances in a laboratory setting?
A magnetic stirrer uses a rotating magnetic field to spin a magnetic stir bar placed in a container of liquid. The spinning stir bar creates turbulence in the liquid, causing the substances to mix together evenly.
What do magnetically soft substances do?
Magnetically soft substances are easily magnetized and demagnetized. They have low coercivity, meaning they can quickly change their magnetic orientation when exposed to a magnetic field. These materials are often used in applications where the magnetic state needs to be easily manipulated, such as in transformers or magnetic shielding.
What is used to separate magnetic material from a mixture of other substances?
A magnet. The magnet will attract the magnetic material to it and so separate the magnetic material from the mixture.
