What are two advantages of artificial magnet over a natural magnet?
Artificial magnets can be easily shaped into different forms and sizes, making them more versatile for various applications compared to natural magnets. The magnetic strength of artificial magnets can be controlled and manipulated through processes like magnetization, allowing for a more customizable and precise magnetic field.
Is a magnet made of lodestone?
a naturally occurring magnet composed of a form of iron called magnetite
Why magnet keepers use to store magnets?

How do the iron filings behave when sprinkled over the bar or horseshoe magnet?
The iron filings align along the magnetic field lines when sprinkled over a bar or horseshoe magnet. This creates a visual representation of the magnetic field around the magnet. The filings cluster at the poles of the magnet where the magnetic field is strongest.
Which of the following could a magnet float over network solid semiconductor superconductor molecular solid?
A superconductor.
Whyb are natural magnets noy used in cranes to lift heavy loads?
Natural magnets are not strong enough to lift heavy loads typically encountered in crane operations. Man-made magnets, such as electromagnets, can be controlled and adjusted to generate the necessary magnetic force to lift heavy objects more efficiently. Additionally, natural magnets can lose their magnetism over time, making them unreliable for industrial applications.
What are two advantages of a natural magnet over electromagnet?
One advantage of a natural magnet is that it does not require any external power source to maintain its magnetic properties, unlike an electromagnet that requires electricity to operate. Natural magnets are typically more stable and retain their magnetism for a longer period of time compared to electromagnets that can lose their magnetic properties when the electric current is removed.

What are the benefits of using an electromagnet rather than a bar manet?
An electro-magnet can be switched on & off - a bar magnet is 'permanent' Think of a scrap-yard. If the magnet they use to pick up huge quantities of metal were permanent, they'd have to manually remove every piece. With an electro-magnet, they simply turn the power on to pick up a load, and off when they want to release it. You can make your own electro-magnet with a battery, some wire and a large nail.
What are the advantages do manufactured boards have over natural woods?
it doesn't break easily
What are the principles of an electric bell?
An electric bell uses electro-magnetism to move a sprng loaded bell striker. A Direct Current bell uses a slightly different approach as the magnetic field does not alternate. In a DC bell, an electro magnet pulls the striker closer (causing the bell to be hit), and a small switch on the striker opens shutting off the current to the electomagnet. A spring returns the striker to its resting place, and the switch is reclosed, allowing the electro-magnet to pull the striker toward it (and the bell), starting the cycle over again.Asjusting the spring tension and the swiching points allows the bell to be adjusted so that the frequency of the strikes (and their relative volume), can be 'tuned' within a small range. Increasing the voltage (and therefore, current) has a similar effect to increase the frequency (e.g. shorten the amount of time between each bell strike), and the volume as the striker has a greater electro magnetic force acting upon it.A buzzer is the identical design, but the striker hits the electromagnet only, and not a bell.It's a Simple Electro-magnetic mechanism. In a bell, there is a circuit for an Electro-Magnetic (which is triggered by the button). This electro magnet is covered by a metal "bowl". Also, there is a metal rod, attached to a stationary end. So, when someone pushes a button, the circuit is closed => electricity go through the Electro Magnet => the metal rod is attracted to the magnet and hit the bowl, creating a sound.
What makes an electro magnet?
An electromagnet is created by wrapping a coil of wire around a metal core and then applying an electric current to the wire. This electric current generates a magnetic field around the coil, effectively turning the metal core into a magnet. Adjusting the strength of the current allows for control over the magnetic force produced by the electromagnet.
What are the advantages disadvantages of nationalisation?
The advantages of nationalism are that they give the government control over the country's Natural Resources, instead of giving it to foreign companies. The disadvantage is that it stifles competition.
Can steel passing over a magnet be recorded?
The EFFECT of steel passing over a magnet can be detected and therefore recorded.
