What factors affect its magnetic properties?
Factors that can affect a magnet’s strength include:
- Heat.
- Radiation.
- Strong electrical currents in close proximity to the magnet.
- Other magnets in close proximity to the magnet.
- Neo magnets will corrode in high humidity environments unless they have a protective coating.
What are the magnetic properties of substances?
Magnetic Properties
| Properties | Description |
|---|---|
| Paramagnetic | They are weakly attracted by the magnetic fields. |
| Ferromagnetic | Strongly attracted by the magnetic field. It can be magnetized permanently |
| Antiferromagnetic | Net magnetic moment is zero. |
| Ferrimagnetic | Possess small net magnetic moments |
What do you mean by magnetic properties of the solid substance?
The magnetic properties of a solid are the result of the magnetic property of the atoms or ions of these solids. More specifically the magnetism and magnetization of a solid will depend on the movement of electrons in an atom. This magnetic behaviour of the electrons of an atom is due to the movement patterns.
Why are some substances magnetic?
Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. In substances such as iron, cobalt, and nickel, most of the electrons spin in the same direction. This makes the atoms in these substances strongly magnetic—but they are not yet magnets.
What factors affect magnetic and electric force?
The four main factors that affect the strength of an electromagnet are the loop count, the current, the wire size, and the presence of an iron core.
How magnetic substances can be classified on the basis of their magnetic characteristics?
On the basis of their magnetic properties, substances can be classified into five categories: (i) paramagnetic (ii) diamagnetic (iii) ferromagnetic (iv) antiferromagnetic and (v) ferrimagnetic. They are weakly magnetized in a magnetic field in opposite direction.
What is it called when a substance is magnetic?
Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field.
What are two factors that affect the strength of magnetic forces *?
The answer is “all of these affect the strength of a magnet” The proximity to the object, the size of the object, the material of the object it is sticking to, and the temperature of the object all affect magnetic pull. Magnetism is the force by which objects are attracted to or repelled by other objects.
