Soft iron is a good example of a material that can be strongly magnetized by an external magnetic field, but which loses most (or nearly all) of its magnetism as soon as the external field is removed. Generally, materials classed as Paramagnetic exhibit this behaviour. Many Ferromagnetic materials are designed to behave this way, such as the Ferrite cores of tuning coils in radio receivers.
What else can I help you with?
Does copper magnetize?
Copper is not a magnetic material and does not magnetize easily.
What is magnetic hardness?
Magnetic hardness refers to the resistance of a material to becoming magnetized. A material with high magnetic hardness will have difficulty becoming magnetized or demagnetized, while a material with low magnetic hardness will magnetize easily. This property is important in applications where a stable magnetic field is required.
What types of magnets are easy to magnetize but lose magnetism quickly?
Temporary magnets, such as soft iron and steel, are easy to magnetize but lose magnetism quickly because they have low coercivity. These types of magnets can be easily demagnetized by external factors such as heat or mechanical shock.
Is aluminum paramagnetic and what are its properties in relation to magnetism?
Yes, aluminum is paramagnetic, which means it is weakly attracted to magnetic fields. Its properties in relation to magnetism include being easily magnetized and demagnetized, having a low magnetic permeability, and not retaining magnetism once the magnetic field is removed.
What is an excellent conductor of magnetic lines of force?
Iron is an excellent conductor of magnetic lines of force due to its high magnetic permeability. This property allows iron to easily attract and retain magnetism, making it a common material used in electromagnets and magnetic cores in transformers and electric motors.
Does copper magnetize?
Copper is not a magnetic material and does not magnetize easily.

A material with high magnetic hardness will have difficulty becoming magnetized or demagnetized, while a material with low magnetic hardness will magnetize easily. This property is important in applications where a stable magnetic field is required.
Distinguish between the magnetic properties of iron and steel?
The magnetic properties of iron are high susceptibility and low retentivity. It means that it is easier to magnetize but also loses magnetism easily. The properties of steel are the opposite of iron.
What role is played by molecular magnets to magnetize and demagnetize bodies?
The relative coercitivity of a material helps to magnetize and demagnetised a substance. If the coercitivity id low then the material can be easily demagnetized and vice versa. A substance can be magnetized by creating magnetic filed of opposite charges and demagnetized by creating same filed of charges.
Does magnetism go through paper?
Yes. Magnetic lines of force penetrate paper with little to no difficulty.
What types of magnets are easy to magnetize but lose magnetism quickly?
Temporary magnets, such as soft iron and steel, are easy to magnetize but lose magnetism quickly because they have low coercivity. These types of magnets can be easily demagnetized by external factors such as heat or mechanical shock.
Does magnetism go through all materials?
yes, magnetism is a non-contact force, just because something is not magnetic doesnt mean it wont go through it, much like gravity except some things are magnetically neutral Magnetic material such as iron can shield enclosures from magnetic lines of force.
Is aluminum paramagnetic and what are its properties in relation to magnetism?
Yes, aluminum is paramagnetic, which means it is weakly attracted to magnetic fields. Its properties in relation to magnetism include being easily magnetized and demagnetized, having a low magnetic permeability, and not retaining magnetism once the magnetic field is removed.
What is an excellent conductor of magnetic lines of force?
Iron is an excellent conductor of magnetic lines of force due to its high magnetic permeability. This property allows iron to easily attract and retain magnetism, making it a common material used in electromagnets and magnetic cores in transformers and electric motors.
Why is soft iron used as the core of an electromagnet strengthens as magnetic ability?
Soft iron is used as the core of an electromagnet because it can easily magnetize and demagnetize, enhancing the magnetic strength. It has high magnetic permeability, allowing magnetic fields to pass through easily and concentrate, increasing the overall magnetic ability of the electromagnet.
Does glass magnetize easily?
No its not a metal.
How can you test if a magnetic or non-magnetic materials are better at allowing the magnetic force to pass through?
You can use a device that detects magnetism. A compass needle may suffice.
